Given the following hypotheses: - Ho: HS 11 H1: M > 11 A random sample of 10 observations is selected from a normal population. The sample mean was 18 and the sample standard 00:53:15 deviation 4.2. Using the 0.01 significance level: a. State the decision rule. (Round your answer to 3 decimal places.) Reject Ho if t> b. Compute the value of the test statistic. (Negative answers should be indicated by a minus sign. Round your answer to 3 decimal places.) Value of the test statistic c. What is your decision regarding the null hypothesis? Ho. There is evidence to conclude that the population mean is greater than 11. Prev 1 of 11 Next >
