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
included?
+36916 You have 16 numbers...... list them in increasing order
add them all then divide the sum by 16 to find the MEAN (= average)
the MEDIAN is the number in the MIDDLE of the list
there really is no MIDDLE number....so take the TWO middle numbers, add them then divide by 2 to find the MEDIAN
The MODE is the number that occurs the most often in the list of numbers...... give it a try ! 
ok! ill try!

Sorted Data Set: 20, 60, 65, 65, 70, 70, 75, 75, 75, 75, 80, 85, 85, 90, 95, 229
+36916 I will assume you got the answer correct.....now you can see the 'outliers' 20 and 229 and remove them and do the calculations without them...
outliers are probably mis-charged (I guess) ...or perhaps the 229 is a multi-room suite ....who knows ?
