A sample of 35 observations is selected from a normal population. The sample mean is 30, and the population standard deviation is 4. Conduct the following test of hypothesis using the .05 significance level. H0 : ? ? 29 H1 : ? > 29
(a) Is this a one- or two-tailed test?
(b) What is the decision rule? (Round your answer to 2 decimal places.) H0 and H1 when z >
(c) What is the value of the test statistic? (Round your answer to 2 decimal places.) Value of the test statistic
(d) What is your decision regarding H0? There is evidence to conclude that the population mean is greater than 29.
(e) What is the p-value?
