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 significance level. 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 -0.879 lies in the region between +2.326 and -2.326.
b. do not reject the null hypothesis because -0.879 lies in the region between +2.5760 and -2.576.
c. reject the null hypothesis because 37% is less than 40%.
d. do not reject the null hypothesis because 37% lies in the area between 0% and 40%.
