Need help with all 3 parts. Thanks

5) The average height of women is y 64 inches, the average height of men is y- 67 inches. For both the standard deviation is abouts 3 inches. (a) Suppose you take a sample of 7 women and 7 men. Construct a 95% CI for both. Do the confidence intervals overlap? repeat using a sample of 117 men and 117 women. Do the confidence intervals (b) Now overlap? (c) Can you explain what happened? Why is sample size important if you're trying to find differences between groups? Statistical comment: comparing Cl's is not the correct way of comparing two groups, but it can give you a pretty good idea if there's a difference).
