The answer is A

now u see that 3 people read between 0 - 2 books

- anonymous

and now there are 2 people that read between 3-5 and 4 people read between 6-8. so that means there are a total of 6 people who read over 2 books

Here are 10 test scores: 73, 74, 76, 77, 78, 79, 80, 80, 82, 84. The mean of these scores is 78.3.
Does this set have an outlier and, if so, how does removing it affect the mean?
A.
The set has 73 as an outlier and removing it decreases the mean by about 0.5.
B.
The set has 73 as an outlier and removing it decreases the mean by about 10.
C.
The set has 73 as an outlier and removing it increases the mean by about 0.5.
D.
This data set has no outliers.

The answer is D because an outlier is a value that does not fit with the set of values, so 30 (or something like that) would be an outlier it's asking for an outlier to the set of values. notice how all the numbers in the set of values are in the 70's or 80's......Making D ur answer
