Question 1

Using the same ESPN report that the average income of an NFL players is 1.5 million (1,500,000) with a population standard deviation of $200,000. If they randomly select 500 players and determine their average income of the sample is $1,485,000. Using 5 step hypothesis testing assuming that the average income is decreasing, what can you conclude based on the p-value?Use a .05 significance level.

B. p-value is less than significance level so DO NOT Reject Ho

A. p-value is less than significance level so Reject Ho

C. p-value is NOT less than significance level so Reject Ho

D. p-value is NOT less than significance level so DO NOT Reject Ho

Question 2

Using the same ESPN report that the average income of an NFL players is 1.5 million (1,500,000) with a population standard deviation of $200,000. If they randomly select 500 players and determine their average income of the sample is $1,485,000. Using 5 step hypothesis testing assuming that the average income is decreasing, which one is your decision rule (rejection region)?Use a .05 significance level.

A. Reject Ho if z > 1.26

D. Reject Ho if -1.96 > z > 1.96

C. Reject Ho if z > 1.96

B. Reject Ho if -1.65 > z > 1.65

Question 3

Develop the null and alternative hypothesis: Wawa claims that the average wait time for a sandwich is different than 2 minutes. Keyword: _________?

Ho: = 2 minutes and HI: 2 minutes

Ho: > 2 minutes and HI: 2 minutes

Ho: >= 2 minutes and HI: < 2 minutes

Ho: 2 minutes and HI: = 2 minutes

Question 4

ESPN reports that the average income of an NFL players is 1.5 million (1,500,000) with a population standard deviation of $200,000. If they randomly select 500 players and determine their average income of the sample is $1,485,000. Which one is the Null and Alternative Hypotheses?Use a .05 significance level.

C. Ho: =$1,500,000HI: not/= $1,500,000

A. Ho: >= $1,500,000 HI: < $1,500,000

B.Ho: <= $1,500,000 HI: > $1,500,000

D. Ho: not/=$1,500,000HI: = $1,500,000
