Question: Suppose that you are testing the hypotheses H0: p = .20 vs. HA: p ? .20. A sample of size 250 results in a sample

Suppose that you are testing the hypotheses H0: p = .20 vs. HA: p ? .20. A sample of size 250 results in a sample proportion of .25.

a. Construct a 95% confidence interval for p.

b. Based on the confidence interval, at a = .05 can you reject H0? Explain.

c. What is the difference between the standard error and standard deviation of the sample proportion?

d. Which is used in computing the confidence interval?
