Question Help<br>Listed below are the amounts of net worth (in millions of dollars) of the ten wealthiest celebrities in a country. Construct a 90% confidence interval. 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.<br>A. Because the ten wealthiest celebrities are not a representative sample, this doesn't provide any information about the population of all celebrities.<br>B. We are 90% confident that the interval from $<br>million to $<br>million actually contains the true mean net worth of all celebrities.<br>(Round to one decimal place as needed.)<br>C. We are confident that 90% of all celebrities have a net worth between $<br>million and $<br>million.<br>(Round to one decimal place as needed.)<br>Do the data appear to be from a normally distributed population as required?<br>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.<br>B. Yes, because the pattern of the points in the normal quantile plot is reasonably close to a straight line.<br>C. 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.<br>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.<br>Click to select your answer(s).<br>Save for Later<br>
