Question: Should H0 be rejected? Use the p-value and a level of significance of 0.05 to justify your answer. Use the above data to construct a 95% confidence interval for p1 - p2

Consider this hypothesis test:

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:

Z0=1.404
p value= 0.0801

Population 1

Population 2

Sample Size (n)

400

600

Number of “yes”

300
