The claim that "40% of those persons who retired from an industrial job before the age of 60 would return to work if a suitable job was available, is to be investigated at the 0.02 level of risk. If 74 out of the 200 workers sampled said they would return to work, what is our decision? Select one: a.Do not reject the null hypothesis because 27% lies in the area between 2% and 40% b.Do not reject the null hypothesis because -0.866 lies in the region between 0 and -2.33 c.Do not reject the nll hypothesis because 37% lies in the area between 0% and 40% O d.Reject the null hypothesis because 37% is less than 40% e.Do not reject the null hypothesis because -0.866 lies in the region between 0 and -2.58
