ARCH (Autoregressive Conditional Heteroscedasticity) models are estimated using Maximum Likelihood (ML) estimation. Regarding Question 7, if the model has the given conditional variance function, it corresponds to an ARCH(3) model.

In the case of ARCH models, the ML estimation process involves the following steps:

1. Specify the ARCH model: Determine the appropriate order of the ARCH model by analyzing the autocorrelation and partial autocorrelation functions of the squared residuals (or other suitable diagnostic tests). For example, an ARCH(3) model implies that the conditional variance at time t depends on the squared residuals at time t-1, t-2, and t-3.

2. Formulate the likelihood function: The likelihood function specifies the probability of observing the given data under the assumed ARCH model. In ARCH models, the likelihood function is constructed based on the assumption that the errors follow a normal distribution with mean zero and a time-varying conditional variance.

3. Maximize the likelihood function: The goal is to find the parameter values that maximize the likelihood function. This is typically achieved using numerical optimization techniques, such as the Newton-Raphson algorithm or the BFGS algorithm.

4. Estimate the parameters: Once the likelihood function is maximized, the estimated parameter values are obtained. These estimates represent the best-fitting values that maximize the likelihood of observing the given data.

Therefore, the answer to Question 7 is: ARCH(3).

Answer:

Step-by-step explanation:

Confidence interval for population proportion is expressed as

Sample proportion ± margin of error

Margin of error = z × √pq/n

Where

z represents the z score corresponding to the confidence level

p = sample proportion. It also means probability of success

q = probability of failure

q = 1 - p

From the information given,

Sample proportion, p = 65/100 = 0.65

q = 1 - 0.65 = 0.35

n = 200

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.025 = 0.975

The z score corresponding to the area on the z table is 1.96. Thus, the z score for a confidence level of 95% is 1.96

Margin of error = 1.96√(0.65)(0.35)/200

Margin of error = 0.066 = 6.6%

The maximum boundary of the interval is

0.65 + 0.066 = 0.716

\(1 \frac{1}{6} \times 9 \\ = \frac{7}{6} \times 9 \\ = \frac{7}{6} \times \frac{9}{1} \\ = \frac{7}{2} \times \frac{3}{1} \\ = \frac{21}{2} \)

Is the ratio 15:12 equivalent to these? No, it's not equivalent.

Why not? Because if we tripled everything in 5:3 then we'd get 15:9. We don't have the second value as 12.

-------------------------------------

Is the ratio 30:18 equivalent to these? Yes it is equivalent

To go from 5:3 to 30:18, we multiply everything by 6

5*6 = 30

3*6 = 18

This shows that 5:3 scales up to 30:18

-------------------------------------

Give two more examples of ratios that are equivalent to 5:3.

Pick any number you want. Let's say we pick 7. Multiply both parts of 5:3 by the value 7

5*7 = 35

3*7 = 21

The ratio 5:3 is equivalent to 35:21

The ratio 5:3 is also equivalent to 50:30 after multiplying both parts by 10.

What is quadratic equation?

A quadratic equation in algebra is any equation that can be written in standard form as where x is an unknown and where a, b, and c denote known numbers, where a ≠ 0.

Let, for x^2 + mx + n = 0

⇒ x = 2α or 2β

From the given condition,

for x^2 + mx + n = 0 ⇒ x = α or x = β

Then,

2(α + β) = -m           ..(1)

4αβ = n                    ..(2)

and α + β = -p         ..(3)

αβ = m                     ..(4)

From equation (1) and (3),

-m/2 = -p

⇒ p = m/2

and from equation (2) and (4),

n/4 = m

⇒ n = 4m

Therefore,

n/p = 4m / (m/2) = 4 x 2 = 8

Hence, n/p = 8.

The domain restrictions of the expression q²−7q−8/q²+3q−4 are q ≠ -4 and q ≠ 1. (option c)

The denominator of the expression is q²+3q−4. To determine the values that would make the denominator equal to zero, we can set it equal to zero and solve for q:

q² + 3q - 4 = 0

Now, we can factorize the quadratic equation:

(q + 4)(q - 1) = 0

To find the values of q, we set each factor equal to zero and solve for q:

q + 4 = 0 or q - 1 = 0

Solving these equations, we get:

q = -4 or q = 1

So, the values of q that would make the denominator equal to zero are q = -4 and q = 1. These are the values we need to exclude from the domain of the expression to avoid division by zero.

There are 10 members on the board, so there are 10 ways to elect a president, 9 ways to elect a vice president, 8 ways to elect a secretary, and 7 ways to elect a treasurer.

This is because each position can be filled by any of the members, except for the position that the member is already filling. For example, the president can be elected from any of the 10 members, but the vice president must be elected from the remaining 9 members.

The company sea esta has ten members on its board of directors, so it has a lot of different options for how to elect a president, vice-president, secretary, and treasurer. One way to elect a president would be to have the board members vote on who they want to be president.

Step-by-step explanation:

can I see the other options for the rest?

200 miles is covered by Keith when the plans have the same price. When both plans have the same price, the cost is $160.

Two rents plans and the costs, the miles traveled by Keith when the two plans cost the same and the cost when the two plans cost the same, quadratic equations will be

Let the total miles covered for each plan be

The cost of the first plan would be

cost of the plan A=40+0.60x

The cost of the second plan would be

Cost of second plan=0.80x

If the two cost is the same, then

\(0.80x=40+0.60x\)

Solve for x by collecting like terms

\(0.80x-0.60x=40\)

\(0.20x=40\)

\(x=\frac{40}{0.20}\)

\(x=200\)

The cost when the two plans cost the same would be

\(0.80x=0.80(200)=160\)

or

\(40+0.60x=40+0.60(200)=160\)

Hence, the miles covered when the plans cost the same is 200 miles.

The cost when the two plans cost the same is $160.

The correct option is C. 0.541, The constant of integration K can be found by setting x = 0 and g(x) = 0. This gives us K = 0.

We can use the following steps to solve this problem:

Here is a more detailed explanation of each step:

We can then use the following steps to solve the integral:

We can now solve this integral using integration by parts. Let u = u and v' = e^-u cos(u). Then du = du and v = -e^-u sin(u).

This gives us g(x) = C [-e^-u sin(u)] + ∫ e^-u sin(u) du.

The integral ∫ e^-u sin(u) du can be solved using integration by parts again. Let u = sin(u) and v' = e^-u. Then du = cos(u) du and v = -e^-u.

This gives us g(x) = C [-e^-u sin(u)] - e^-u cos(u) + ∫ e^-u cos(u) du.

The integral ∫ e^-u cos(u) du can be solved using integration by parts again. Let u = cos(u) and v' = e^-u. Then du = -sin(u) du and v = -e^-u sin(u).

This gives us g(x) = C [-e^-u sin(u)] - e^-u cos(u) + e^-u sin(u) + K.

The constant of integration K can be found by setting x = 0 and g(x) = 0. This gives us K = 0.

This gives us the final solution for g(x): g(x) = -e^-u sin(u) - e^-u cos(u).

Evaluating g(4). We know that g(4) = 0.325. We can use this value to find the constant of integration in the solution to the differential equation.

To do this, we can set x = 4 and g(x) = 0.325 in the solution to the differential equation. This gives us -e^-4 sin(4/100) - e^-4 cos(4/100) = 0.325.

We can solve this equation for the constant of integration K. This gives us K = 0.325 + e^-4 sin(4/100) + e^-4 cos(4/100).

Evaluating g(1). We can now evaluate g(1) using the value of the constant of integration and the solution to the differential equation.

To do this, we can set x = 1 and g(x) = 0.541 in the solution to the differential.

For the given scenario: the Probability of making both shots are A. 0.64 and B. 0.72

a) If a player makes 80% of his foul shots, the probability of making a single foul shot is 0.8. Since the two shots are considered independent events, the probability of making both shots is the product of the individual probabilities.

Therefore, the probability of making both shots is 0.8 * 0.8 = 0.64.

To calculate the probability of making exactly one shot, we need to consider two scenarios: making the first shot and missing the second, or missing the first shot and making the second. Each scenario has a probability of 0.8 * 0.2 = 0.16.

Therefore, the probability of making exactly one shot is 0.16 + 0.16 = 0.32.

Similarly, the probability of missing both shots is 0.2 * 0.2 = 0.04.

b) In this case, the outcome of the second shot depends on the outcome of the first shot. If the player makes the first shot (with a probability of 0.8), the probability of making the second shot is 0.9.

Therefore, the probability of making both shots is 0.8 * 0.9 = 0.72.

If the player misses the first shot (with a probability of 0.2), the probability of making the second shot is 0.7.

Therefore, the probability of making exactly one shot is 0.2 * 0.7 = 0.14.

Since there are only two possible outcomes (making both shots or making exactly one shot), the probability of neither shot being made is 1 - (0.72 + 0.14) = 0.14.

Therefore, for the given scenario:

a) Probability of making both shots: 0.64

  Probability of making exactly one shot: 0.32

  Probability of missing both shots: 0.04

b) Probability of making both shots: 0.72

  Probability of making exactly one shot: 0.14

(2) False. The p-value is the probability of obtaining the observed results or more extreme results if the null hypothesis is true.

False. A p-value of .4 means we should not necessarily accept that the null hypothesis is true. The p-value represents the probability of obtaining a result as extreme or more extreme than the one observed, assuming the null hypothesis is true. A common threshold to reject the null hypothesis is a p-value less than 0.05. Since 0.4 is greater than 0.05, we do not have enough evidence to reject the null hypothesis, but it does not mean we should accept it as true.

False. The p-value is not the probability that the null hypothesis is true. It is the probability of observing the given results (or more extreme results) assuming the null hypothesis is true.
