Internal validity explains the association between binge-watching tv and irritability.

In the context of a specific study, internal validity refers to how strongly a piece of evidence supports a claim regarding cause and effect. It is one of the most crucial characteristics of scientific research and a crucial idea when considering evidence more generally.

The extent to which alternative explanations for a study's findings (often, sources of systematic error or "bias") can be ruled out is a measure of its internal validity. In contrast, external validity measures how well data support judgments made regarding other situations (that is, the extent to which results can be generalized).

We cannot find the value of g(6) and we cannot evaluate the expression g(g(0)).

f(g(1)):

First of all, we need to find the value of g(1). To do this, we need to find 1 on the x-axis and then find the corresponding value on the y-axis. When we do this, we see that g(1) = 4.

So now we can substitute 4 for g(1) in the expression f(g(1)).So, f(g(1)) = f(4). To find the value of f(4),

we go to the graph of f(x) and find the point where x = 4. When we do this, we see that f(4) = -1. Therefore, f(g(1)) = f(4) = -1. g(f(3)): We first need to find f(3).

To do this, we go to the graph of f(x) and find the point where x = 3. When we do this, we see that f(3) = 2. So now we can substitute 2 for f(3) in the expression g(f(3)).

So, g(f(3)) = g(2). To find the value of g(2), we go to the graph of g(x) and find the point where x = 2. When we do this, we see that g(2) = 5. Therefore, g(f(3)) = g(2) = 5.

f(f(4)): We first need to find f(4). To do this, we go to the graph of f(x) and find the point where x = 4. When we do this, we see that f(4) = -1. So now we can substitute -1 for f(4) in the expression f(f(4)).

So, f(f(4)) = f(-1). To find the value of f(-1), we go to the graph of f(x) and find the point where x = -1. Since there is no point for x = -1 on the graph of f(x), we cannot find the value of f(-1).

Therefore, we cannot evaluate the expression f(f(4)). g(g(0)): We first need to find g(0). To do this, we go to the graph of g(x) and find the point where x = 0.

When we do this, we see that g(0) = 6. So now we can substitute 6 for g(0) in the expression g(g(0)).

So, g(g(0)) = g(6). To find the value of g(6), we go to the graph of g(x) and find the point where x = 6. When we do this, we see that there is no point for x = 6 on the graph of g(x).

To price the derivative using the two-period binomial model, we need to calculate the expected payoff of the derivative using the risk-neutral probabilities.

The possible outcomes for the two-period binomial model are H and T,  there are four possible states of the world: HH, HT, TH, and TT.

To calculate the expected payoff we need to calculate the probability of each state occurring. The probability of HH occurring is pp=0.60.6=0.36, the probability of HT and TH occurring is pq+qp=0.60.4+0.40.6=0.48, and the probability of TT occurring is qq=0.40.4=0.16.

Next, we can calculate the expected payoff in HH and TT states, the derivative pays off 1, and in the HT and TH states, the derivative pays off 0. The expected payoff of the derivative in the HH and TT states is 10.36=0.36, and the expected payoff in the HT and TH states is 00.48=0.

We need to discount the expected payoffs back to time 0 using the risk-neutral probabilities.

The probability of that state occurring multiplied by the discount factor, which is 1/(1+r), where r is the risk-free interest rate.

Since this is a risk-neutral model, the risk-free interest rate is equal to 1. Therefore, the risk-neutral probability of each state occurring is

HH: 0.36/(1+1) = 0.18

HT/TH: 0.48/(1+1) = 0.24

TT: 0.16/(1+1) = 0.08

Finally, we can calculate the price of the derivative

Price = 0.181 + 0.240 + 0.240 + 0.081 = 0.26

Therefore, the price of the derivative is 0.26.

The probability of mission success if at least 11 of the 16 patrol boats must operate for the duration of the 20-hour mission if each boat has a failure rate of 1 failure per 100 hoursis 99.5%. Hence, the correct option is (A).

To determine the probability of mission success, we'll need to calculate the probability of failure for each boat and then use the binomial probability formula.

Here are the steps:

1. Calculate the probability of failure for each boat during the 20-hour mission: Since each boat has a failure rate of 1 failure per 100 hours, the probability of failure for each boat in 20 hours is 20/100 = 1/5 or 0.2.

2. Calculate the probability of success for each boat: The probability of success for each boat is 1 - probability of failure = 1 - 0.2 = 0.8.

3. Use the binomial probability formula to find the probability of at least 11 boats operating successfully:
P(X ≥ 11) = 1 - P(X ≤ 10), where X is the number of successful boats.

4. Calculate P(X ≤ 10) using the binomial probability formula:

P(X ≤ 10) = ∑[C(16, k) × (0.8)^k × (0.2)^(16-k)], where k ranges from 0 to 10, and C(16, k) is the binomial coefficient or the number of ways to choose k successes from 16 boats.

5. Calculate 1 - P(X ≤ 10) to get the probability of mission success.

After performing the calculations, the probability of mission success is found to be approximately 99.5%, which corresponds to option A.

So, the probability of mission success, given that at least 11 of the 16 patrol boats must operate for the duration of the 20-hour mission and each boat has a failure rate of 1 failure per 100 hours, is approximately 99.5%.

Hence, option (A) is correct.

To estimate ∫402 using left endpoints for =5 approximating rectangles, we need to calculate the width and height of each rectangle.

The width of each rectangle is determined by dividing the total interval, in this case, 2, by the number of rectangles, which is 5. Therefore, the width of each rectangle is 2/5 = 0.4.

Next, we need to find the height of each rectangle. Since we are using left endpoints, we evaluate the function at the left endpoint of each rectangle. In this case, the left endpoints are 40, 40.4, 40.8, 41.2, and 41.6.

Now, we calculate the height of each rectangle by evaluating the function, which is 2x, at these left endpoints. The height of each rectangle is: 2(40) = 80, 2(40.4) = 80.8, 2(40.8) = 81.6, 2(41.2) = 82.4, and 2(41.6) = 83.2.

Finally, we multiply the width and height of each rectangle and sum them up to estimate the value of the integral.

The estimate for ∫402 using left endpoints for 5 approximating rectangles is: 0.4(80) + 0.4(80.8) + 0.4(81.6) + 0.4(82.4) + 0.4(83.2) = 329.6.

In conclusion, ∫402 is approximately 329.6 when using left endpoints for 5 approximating rectangles.

In linear regression, the variance around the regression line represents the variability of the dependent variable (response variable) that is not explained by the regression model.

It measures the dispersion of the actual data points around the predicted values from the regression line.

The variance around the regression line can vary with different values of the predictor variable. This is because the relationship between the predictor variable and the response variable may not be constant across the entire range of the predictor variable. In other words, the spread or dispersion of the data points around the regression line may change as the predictor variable changes.

By examining the residuals (the differences between the observed values and the predicted values from the regression line) and calculating their variances, you can assess the variability of the data points around the regression line. This variability is an important aspect of understanding the goodness of fit of the regression model and the accuracy of the predictions.
