Given the following hypothesis:
H0 : μ = 122
H1 : μ ≠ 122
A random sample of six resulted in the following values 133, 129, 130, 131, 137, and 129.
Using the 0.10 significance level, can we conclude the mean is different from 122?
(a) What is the decision rule? (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
Reject H0 : μ = 122 and fail to reject H1 : μ ≠ 122 when the test statistic is
(b) The value of the test statistic is (Round your answer to 3 decimal places.)
