Question
I need help with 2.(a,b,c,d,e,f,g,h,i,i,ii)
c. Is it reasonable to assume that this data is normally distributed? Explain your answer.
Yes, this data has normal distribution because it appears to have a bell shape, which means that the
majority of the time, Larry made between 170 and 180 3-point shots, with few practice days where he
made fewer shots and few practice days where he made lots (close to 200 shots) of shots.

h. Based upon the totality of your analysis, compare the calorie contents of beef and poultry hot dogs.
When comparing the beef hot dogs
the poultry hot dogs, the mean and median calorie content is
greater in the beef hot dogs than it is in the poultry hot dogs. About 75% of the beef hot dogs have more
than 140 calories and about 75% of the poultry hotdogs have less than 140 calories, therefore, the
variation measure are about the same.
Suppose that you were to go to a cook-out where there were two grills. On one grill, there are only beef
hot dogs being grilled. On the other grill, there are only poultry hot dogs being grilled. Suzy is very
i.
calorie conscious because of her new diet.
i. To which grill should Suzy go for her hot dog?
Suzy should eat the poultry hot dogs which have less calories since she is watching her caloric
intake.
ii. If Lights Out Larry (Suzy's boyfriend) were to go to the other grill, could Suzy be absolutely sure
that the calorie content of her hot dog is less than the calorie content of Larry's hot dog?
Explain your answer.
No, some poultry hot dogs have almost as many calories as some of the beef hot dogs as seen
on the boxplots, so it is possible that Suzy may get a higher calorie poultry hot dog.
