3. The cost of hotel rooms at Stay in
Comfort range from $49 to $229 per
night. Here are the rates charged, in
dollars, for one particular night:
70, 75, 85, 65, 75, 90, 70, 75, 60, 80, 95,
85, 75, 20, 65, 229
a) Calculate the mean, median,
and mode costs.
b) Identify the outliers.
How can you explain these costs?
c) Calculate the mean, median, and
mode costs without the outliers.
How is each average affected
when the outliers are not
d) Should the outliers be used
when reporting the average cost
of a hotel room? Explain.
a) To calculate the mean, add all the numbers and divide by the number of numbers.
To calculate the median, arrange the numbers from smallest to largest and choose the number in the middle;
since there is an even number of numbers find the midpoint between the two numbers in the center of the data.
To calculate the mode, find the number that is used most often.
b) Outliers are numbers that are very far from the other numbers. This set of data has two outliers, one very
small and the other very large.
c) Repeat the steps of part a), but do not use the outliers; compare these new answers to your old answers,
then answer this question.
d) This is an opinion question for you to decide.
THAT'S REALLY RUDE. You should thank Geno for trying to help. This website isn't for giving you answers. Come on. Now you post it how many? 4 times. I answered you there, so be grateful and don't blame others for stuff you did. Could you tell me where this came from and why you need answers so badly?
