SET THREE: Chapter 6, Section 1-HT, Exercise 046 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^=0.60 with n=25 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...
