Given the following hypothesis:
H0 : μ ≤ 11
H1 : μ > 11
For a random sample of 10 observations, the sample mean was 13and the sample standard deviation 4.20. Using the .05 significancelevel:
(a) State the decision rule. (Round your answer to 3 decimalplaces.)
Reject or don't reject? H0 if t > ?
(b) Compute the value of the test statistic. (Round your answerto 2 decimal places.)
Value of the test statistic :
(c) What is your decision regarding the null hypothesis?
(Reject or dont reject?) H0. The mean (is or is not) greaterthan 11.
