Carry out the test at the 5% level of significance, so
you need to state whether you accept or reject the null hypothesis
are the 5% level of significance.
We have a population of 500. If we assume a population standard
deviation of 3.5 hours spent watching tv, test the hypothesis that
the population mean would be at least 14 hours against a one tail
alternative, using a level of significance of 5 percent. The mean
of the data is equal to 13.52 hours spent watching tv .
