Consider the following hypothesis test. 0: 39:20 Ho: M = 22 Ha: M # 22 A sample of 75 is used and the population standard deviation is 10. Compute the p-value and state your conclusion for each of the following sample results. Use a = 0.01. (Round your test statistics to two decimal places and your p-values to four decimal places.) (a) x = 24 Find the value of the test statistic. Find the p-value. p-value = State your conclusion. O Do not reject Ho. There is sufficient evidence to conclude that u # 22. O Do not reject Ho. There is insufficient evidence to conclude that u # 22. O Reject Ho. There is insufficient evidence to conclude that u # 22. O Reject Ho. There is sufficient evidence to conclude that M $ 22.
