Question

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**
