A sample of 34 observations is selected from a normalpopulation. The sample mean is 30, and the population standarddeviation is 3. Conduct the following test of hypothesis using the0.05 significance level:
H0: ĂŽÂĽ = 31
H1: μ ≠31
a. Is this a one- or two-tailed test?

b. What is the decision rule?
Reject H0 and accept H1when z does not lie in the regionfrom  to  .
c. What is the value of the test statistic?(Negative answer should be indicated by a minus sign. Roundthe final answer to 2 decimal places.)
