H0: p1 - p2 = 0

Ha: p1 - p2 > 0

Here p1 is the population proportion of "yes" of Population 1 and p2 is the population proportion of "yes" of Population 2. Use the statistics data from a simple random sample of each of the two populations to complete the following:

Population 1 Population

Sample Size (n) 400 600

Number of "yes" 300 426

a. Compute the test statistic z.

b. What is the p-value?

c. Should H0 be rejected? Use the p-value and a level of significance of 0.05 to justify your answer.

d. Use the above data to construct a 95% confidence interval for p1 - p2
