Answer
A. is this a one-or two- tailed test?
Hο: μ≤ 10
Hı: μ > 10
This is a one tailed test as the alternative hypothesis is have a > sign. For a two tailed test the alternative hypothesis have ≠ sign .
B. What is the decision rule?
Reject the null hypothesis if the calculated value of Z is greater than the critical value of Z at 0.02 significance ...
