Given the following hypothesis:
H0 : μ ≤ 11
H1 : μ > 11
For a random sample of 10 observations, the sample mean was 12 and the sample standard deviation 3.80. Using the .025 significance level:
(a) State the decision rule. (Round your answer to 3 decimal places.)
(b) Compute the value of the test statistic. (Round your answer to 2 decimal places.)
