A sample of 33 observations is selected from a normal population. The sample mean is 30, and the population standard deviation is 3. Conduct the following test of hypothesis using the 0.05 significance level.
- H0 : μ<= 29
- H1 : μ > 29

What is the value of the test statistic?1.91
What is your decision regarding H0?Reject
There is not evidence to conclude that the population mean is greater than 29.
What is the p-value?0.0278
