Use the normal distribution and the given sample
Use the normal distribution and the given sample results to complete the test of
the given hypotheses. Assume the results come from a random sample and use a 5%
significance level.
Test H0 : p=0.5
vs Ha : p>0.5
using the sample results p^=0.64
with n=75
Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places.
