We wish to estimate what percent of adult residents in a certain county are parents. Out of 200 adult residents sampled, 110 had kids. Based on this, construct a 99% confidence interval for the proportion ππ of adult residents who are parents in this county. Give your answers as decimals, to three places.  < ππ <

A researcher surveyed 12 men who lost their fathers earlier in their lives.  His survey included the age of the subjects when their fathers died and their confidence that they would someday be happily married themselves (100 point scale – higher score = more confidence).  The results are shown below. Mx=15                My =60 SSx=348            SSy=5198 SPxy=933 Age Confidence Rating 12 34 8 30 11 89 21 69 15 55 7 38 18 78 23 66 22 89 19 79 9 35 15 58 Can you estimate a confidence rating for a man who lost his father at 30 years old? Why or why not?
