A Sample of 35 observations is selected from a normal population. The sample mean is 26, and the population standard deviation is 4. Conduct the following test of hypothesis using the 0.05 significance level. H_0: mu = 25 H_1: mu = 25 is this a one or two-labled So ? "One-tailed"-line alternate hypothesis is greater than direction. "Two-tailed"-the alternate hypothesis is different from direction. What is the decision rule? (Round your answer to 3 decimal places.) H_3 when z > What is the value of the test statistic? (Record your answer to 2 decimal places.) Value of the test statistic What is your decision regarding H_0? Do not reject Reject There is evidence to conclude that the population mean is greater than 25 What is the p-value? (Record your answer to 4 decimal places.) p-value
