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.

test statistic =

p-value =
