A. The significance (or alpha) level.

B. The sample proportion.

C. The claimed population proportion.

D. The sample size.

E. All of the above need to be known in order to compute the test statistic.

9. It is claimed that 75% of parents believe their children spend too much time playing video games. If we were to conduct a hypothesis test based on this claim, what should the null hypothesis be?
A. Ho: = 0.75

B. Ho: p = 0.75

D. All of the above are correct.

E. None of the above are correct.

10. Consider a hypothesis testing situation in which the null hypothesis is p = 0.5 and the alternative is p > 0.5. Data is gathered from a random sample and a test statistic of 2.1 is computed. This means our p-value would have to be   
A. less than 0.01.

B. between 0.01 and 0.05.

C. between 0.05 and 0.10

D. greater than 0.10.
