Use the
the given hypotheses. Assume the results come from a random sample and use
a 5% significance level.
Test ??0: p = 0.25 vs ????: p < 0.25 using the sample results ??̂=0.13 with n = 100
Round your answer for the test statistic to two decimal places, and your answer for
the p-value to three decimal places.
a. Briefly state why this sample satisfies the CLT requirements.
b. Find the test statistic. Show all work for full credit. Round to two decimal places.
c. Find the p-value. Include a Statkey pic or provide a sketch that supports your answer.
d. Give the formal decision for this test based on your p-value in part c. Provide a
general conclusion for this test
