7. Listed below are the amounts of net worth (in millions of dollars) of the ten wealthiest celebrities in a country. Construct a 99% confidence interval. What does the result tell us about the population of all celebrities? Do the data appear to be from normally distributed population as required? 256 219 189 170 161 150 145 145 145 140 What is the confidence interval estimate of the population mean u? 2$ million < µ < $ million (Round to one decimal place as needed.) What does the result tell us about the population of all celebrities? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A. We are 99% confident that the interval from $ million to $ million actually contains the true mean net worth of all celebrities. (Round to one decimal place as needed.) O B. We are confident that 99% of all celebrities have a net worth between $ million and $ million. (Round to one decimal place as needed.) O C. Because the ten wealthiest celebrities are not a representative sample, this doesn't provide any information about the population of all celebrities. Do the data appear to be from a normally distributed population as required? O A. No, because the points lie reasonable close to a straight line, but there is a systematic pattern that is not a straight line pattern. O B. No, but the points in the normal quantile plot lie reasonably close to a straight line and show some systematic pattern that is a straight line pattern. OC. Yes, because the pattern of the points in the normal quantile plot is reasonably close to a straight line. OD. Yes, but the points in the normal quantile plot do not lie reasonably close to a straight line or show a systematic pattern that is a straight line pattern.
