Given the following hypotheses: H0: μ ≤ 11 H1: μ > 11 A random sample of 10 observations is selected from a normal population. The sample mean was 12 and the sample standard deviation was 5.0. Using the 0.025 significance level: State the decision rule. (Round your answer to 3 decimal places.) Compute the value of the test statistic. (Negative answers should be indicated by a minus sign. Round your answer to 3 decimal places.) What is your decision regarding the null hypothesis?
