The given statement "Measuring the entire population is usually preferred over measuring a sample from the population" is False because measuring the entire population is often impractical or impossible.

When dealing with large populations, it is typically more feasible to gather data from a representative sample rather than measuring the entire population. This approach saves time, resources, and effort. Sampling allows statisticians to make reliable inferences about the population based on the characteristics observed in the sample.

Carefully chosen samples can accurately reflect the population's attributes and provide valuable insights.

However, it is crucial to ensure that the sample is representative and unbiased to avoid potential sampling errors and ensure the validity of the conclusions drawn from the data.

1. The minimum number of chickens you should purchase to be 95% confident you will have enough food for a night is 44 chickens

2. The probability of running out of food by the end of the night is approximately P(X > 40) ≈ 0.000000000007

To be 95% confident that you will have enough food for a night, you need to calculate the 95% confidence interval for the number of customers that will arrive.

The 95% confidence interval for the number of customers that will arrive is given by

CI = x ± zα/2 * σ/√n

where

x is the sample mean,

zα/2 is the critical value of the standard normal distribution for the desired confidence level (z0.025 = 1.96 for 95% confidence),

σ is the standard deviation of the Poisson distribution (σ = sqrt(λ) = sqrt(40) ≈ 6.325), and

n is the sample size.

Substitute the values

CI = 40 ± 1.96 * 6.325/√40 ≈ 40 ± 3.95

Thus, the minimum number of chickens you should purchase to be 95% confident you will have enough food for a night is 44 chickens.

If you have 10 chickens, the number of customers you can serve is limited to 40 (since each customer requires 4 chickens).

Therefore, the probability of running out of food by the end of the night is given by

P(X > 40) = 1 - P(X ≤ 40)

where X is the number of customers that arrive.

Using the Poisson distribution, we can calculate:

\(P(X \leq 40) = e^-\lambda* \sum(\lambda^k / k!)\)

for k = 0, 1, 2, ..., 40.

P(X ≤ 40) = \(e^-40\) * Σ(\(40^k\) / k!) ≈ 0.999999999993

Therefore, the probability of running out of food by the end of the night is approximately P(X > 40) ≈ 0.000000000007

Question 2 You are operating a Fried Chicken restaurant named "Chapman's Second Best Chicken and Waffles" In a given night you are open to customers from 5pm to 9pm When you are open, customers arrive at an average rate of 5 people every 30 minutes. Individuals are equally likely to arrive at any point in time, and previous arrivals do not impact the probability of additional arrivals. You can handle a maximum of 100 customers a night. On any given night, the amount that guests on average spend at your restaurant is uniformly distributed between $10 and $30 (to be clear, it is the overall average level of spending per guest which is uniformly distributed, not the spending of each individual guest) The distribution of spending per-person is statistically independent of the number of guests that arrive on a given night. 2.1 For every customer you need to purchase 4 chickens. What is the minimum amount of chickens should you purchase to be 95% confident you will have enough food for a night? (note, you can only purchase a whole number of chickens) 2.2 If you have 10 chickens, what is the probability that you will run out of food by the end of the night?

Step-by-step explanation:

The expression G(A+H) - G(A)/2 simplifies to (2A + H + 1)/(3A - 6).

To evaluate the expression G(A+H) - G(A)/2, we first substitute A+H and A into the expression G(Z) = Z + 1/(3Z - 2).

Let's start with G(A+H):

G(A+H) = (A + H) + 1/(3(A + H) - 2)

Next, we substitute A into the function G(Z):

G(A) = A + 1/(3A - 2)

Substituting these values into the expression G(A+H) - G(A)/2:

(G(A+H) - G(A))/2 = [(A + H) + 1/(3(A + H) - 2) - (A + 1/(3A - 2))]/2

To simplify this expression, we need to find a common denominator for the fractions. The common denominator is 2(3A - 2)(A + H).

Multiplying each term by the common denominator:

[(A + H)(2(3A - 2)(A + H)) + (3(A + H) - 2)] - [(2(A + H)(3A - 2)) + (A + H)] / [2(3A - 2)(A + H)]

Simplifying the numerator:

(2(A + H)(3A - 2)(A + H) + 3(A + H) - 2) - (2(A + H)(3A - 2) + (A + H)) / [2(3A - 2)(A + H)]

Combining like terms:

(2A^2 + 4AH + H^2 + 6A - 4H + 3A + 3H - 2 - 6A - 4H + 2A + 2H) / [2(3A - 2)(A + H)]

Simplifying the numerator:

(2A^2 + H^2 + 9A - 3H - 2) / [2(3A - 2)(A + H)]

Finally, we can write the simplified expression as:

(2A^2 + H^2 + 9A - 3H - 2) / [2(3A - 2)(A + H)]

Answer:

B, C, E

Step-by-step explanation:

right on edge

Let's use "l" to represent the length and "w" to represent the width.

From the problem, we know that:

- l = w + 6 (since the length exceeds the width by 6 inches)
- 2l + 2w = 148 (since the perimeter of a rectangle is the sum of the lengths of all four sides, which is 2 times the length plus 2 times the width)

Now we can use substitution to solve for one of the variables. Let's use the first equation to solve for l:

l = w + 6

Substitute this expression for l in the second equation:

2l + 2w = 148

2(w + 6) + 2w = 148

Distribute the 2:

2w + 12 + 2w = 148

Combine like terms:

4w + 12 = 148

Subtract 12 from both sides:

4w = 136

Divide both sides by 4:

w = 34

Now that we know the width is 34 inches, we can use the first equation to find the length:

l = w + 6 = 34 + 6 = 40

So the length is 40 inches and the width is 34 inches.

The complete simplification of the quadratic equation can be determined by applying the following method as follows;

The given solution of Darcy;

x = (-4 ± √28)/2

Using the linear approximating polynomial, e^(-0.7) is approximately 1.7, and using the quadratic approximating polynomial, e^(-0.7) is approximately 1.945.

To find the linear approximating polynomial, we need the first-degree Taylor polynomial centered at a = 0. The linear approximating polynomial is given by p_1(x) = f(a) + f'(a)(x - a), where f(x) = e^(-x).

First, we find f(a) and f'(a):

f(a) = f(0) = e^0 = 1

f'(a) = f'(0) = -e^0 = -1

Substituting these values into the linear approximating polynomial, we get:

p_1(x) = 1 - 1(x - 0) = 1 - x

b. To find the quadratic approximating polynomial, we need the second-degree Taylor polynomial centered at a = 0. The quadratic approximating polynomial is given by p_2(x) = f(a) + f'(a)(x - a) + (1/2)f''(a)(x - a)^2.

First, we find f''(a):

f''(a) = f''(0) = -f'(0) = -(-1) = 1

Substituting all the values into the quadratic approximating polynomial, we get:

p_2(x) = 1 - 1(x - 0) + (1/2)(1)(x - 0)^2

= 1 - x + (1/2)x^2

= 1 - x + (1/2)x^2

c. Using the linear approximating polynomial p_1(x) = 1 - x, we can approximate e^(-0.7) by substituting x = -0.7:

p_1(-0.7) = 1 - (-0.7) = 1 + 0.7 = 1.7

Using the quadratic approximating polynomial p_2(x) = 1 - x + (1/2)x^2, we can approximate e^(-0.7) by substituting x = -0.7:

p_2(-0.7) = 1 - (-0.7) + (1/2)(-0.7)^2 = 1 + 0.7 + (1/2)(0.49) = 1 + 0.7 + 0.245 = 1.945
