A simple random sample of size nequals 40 is drawn from a population. The sample mean is found to be 110.6 ​, and the sample standard deviation is found to be 23.3 . Is the population mean greater than 100 at the alpha equals0.01 level of​ significance?

Determine the null and alternative hypotheses.

Compute the test statistic.​(Round to two decimal places as​ needed.)

Determine the​ P-value.

What is the result of the hypothesis​ test?

the null hypothesis because the​ P-value is   the level of significance. At the a= 0.01 level of​ significance, the population mean
