Question 10 (1 point)

It is reported in USA Today that the average flight cost nationwide is $508.524. You have never paid close to that amount and you want to perform a hypothesis test that the true average is actually greater than $508.524. The hypotheses for this situation are as follows: Null Hypothesis: μ ≤ 508.524, Alternative Hypothesis: μ > 508.524. A random sample of 37 flights shows an average cost of $503.111 with a standard deviation of $59.6514. What is the test statistic and p-value for this test?

Question 10 options:

	1) Test Statistic: 0.552, P-Value: 0.2922
	2) Test Statistic: 0.552, P-Value: 0.7078
	3) Test Statistic: -0.552, P-Value: 1.4156
	4) Test Statistic: -0.552, P-Value: 0.2922
	5) Test Statistic: -0.552, P-Value: 0.7078

Question 11 (1 point)

Consumers Energy states that the average electric bill across the state is $98.33. You want to test the claim that the average bill amount is actually greater than $98.33. The hypotheses for this situation are as follows: Null Hypothesis: μ ≤ 98.33, Alternative Hypothesis: μ > 98.33. You complete a randomized survey throughout the state and perform a one-sample hypothesis test for the mean, which results in a p-value of 0.9117. What is the appropriate conclusion? Conclude at the 5% level of significance.

Question 11 options:

	1) We did not find enough evidence to say the true average electric bill is less than $98.33.
	2) We did not find enough evidence to say a significant difference exists between the true average electric bill and $98.33.
	3) The true average electric bill is less than or equal to $98.33.
	4) The true average electric bill is significantly greater than $98.33.
	5) We did not find enough evidence to say the true average electric bill is greater than $98.33.

Question 12 (1 point)

Suppose the national average dollar amount for an automobile insurance claim is $788.5. You work for an agency in Michigan and you are interested in whether or not the state average is greater than the national average. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 788.5, Alternative Hypothesis: μ > 788.5. You take a random sample of claims and calculate a p-value of 0.0851 based on the data, what is the appropriate conclusion? Conclude at the 5% level of significance.

Question 12 options:

	1) The true average claim amount is less than or equal to $788.5.
	2) The true average claim amount is significantly higher than $788.5.
	3) We did not find enough evidence to say a significant difference exists between the true average claim amount and $788.5.
	4) We did not find enough evidence to say the true average claim amount is less than $788.5.
	5) We did not find enough evidence to say the true average claim amount is higher than $788.5.
