Question

Does age make a difference in the amount of savings a worker feels is needed to be secure at retirement? A study by Comm Sciences for Transamerica Asset Management found that .24 of workers in the 25–33 age category feel that $250,000 to $500,000 is enough to be secure at retirement.However,.35 of the workers in the 34–52 age category feel that this amount is enough. Suppose 210 workers in the 25–33 age category and 176 workers in the 34–52 age category were involved in this study. Use these data to construct a 90% confidence interval to estimate the difference in population proportions on this question.
