Asample of 47 observations is selected from a normal population. the sample mean is 30, and the population standard deviation is 5. conduct the following test of hypothesis using the 0.05 significance level. h0 : μ ≤ 29 h1 : μ > 29
a. is this a one- or two-tailed test? "two-tailed"-the alternate hypothesis is different from direction. "one-tailed"-the alternate hypothesis is greater than direction.
b. what is the decision rule? (round your answer to 3 decimal places.) h0, when z > 1.645
c. what is the value of the test statistic? (round your answer to 2 decimal places.) value of the test statistic 1.37
