Question

The Employee Benefit Research Institute reports that 40% of males anticipate having enough money to live comfortably in retirement, but only 32% of females express that confidence. The results were based on random samples of 100 people of each sex. (a) Would you consider this strong evidence that men and women have different outlook towards life in retirement? Use the critical value method to arrive at a decision. (b) Estimate the difference in the two population proportions with a 95% confidence interval.

Answer 1

Since 0 lies in the above confidence interval.

Hence we can conduct that there is no difference between the men and women outlooks towards life in retirement.
