Thank you for your help

Listed below are the amounts of net worth (in millions of dollars) of the ten wealthiest celebrities in a country. Construct a
95% confidence interval. What does the result tell us about the population of all celebrities? Do the data appear to be from a
normally distributed population as required?

205
183
169
164

What is the confidence interval estimate of the population mean u?
S million < µ<s 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.
O A.
We are confident that 95% of all celebrities have a net worth between $
million and $
million.
(Round to one decimal place as needed.)
O B. Because the ten wealthiest celebrities are not a representative sample, this doesn't provide any information about
the population of all celebrities.
Oc.
We are 95% 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. 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.
B. No, because the points lie reasonable close to a straight line, but there is a systematic pattern that is not a straight
line pattern.
OC. 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.
O D. Yes, because the pattern of the points in the normal quantile plot is reasonably close to a straight line.
