Suppose you want to conduct the following hypothesis testing. Ho : H = 50 against the alternative Ha: J > 50 Summary Statistic based on the Data: n=64, Sample mean = 52.4, Sample SD = 13.521 a. What kind of test would you use (z test or t test etc.)? b. What is the observed value of the test statistic? c. What is the p-value of this test ? d. If significance level is 0.10, then what would be your conclusion (reject HO or Fail to Reject HO)
