Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice.A. Because the ten wealthiest celebrities are not a representative sample, this doesn't provide any information about the population of all celebrities.B. We are confident that 90% of all celebrities have a net worth between $million and $million.(Round to one decimal place as needed.)O C. We are 90% 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.)Do the data appear to be from a normally distributed population as required?O A. Yes, because the pattern of the points in the normal quantile plot is reasonably close to a straight line.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.O C. 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 D. 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.MacBookF7888F6吕0F5F4F3F2F1&esc#76412YUTE- RW%24
