B.
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.
-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.)
-We are confident that
90% of all celebrities have a net worth between
$_____ million and $____
million.(Round to one decimal place as needed.)
-Because the ten wealthiest celebrities are not a representative sample, this doesn't provide any information about the population of all celebrities.
C.
Do the data appear to be from a normally distributed population as required?
-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.
-No, because the points lie reasonable close to a straight line, but there is a systematic pattern that is not a straight line pattern.
-Yes, because the pattern of the points in the normal quantile plot is reasonably close to a straight line.
-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.
