Answer:

6 scores

Step-by-step explanation:

First find mean by adding up all the data and dividing by 6:

Mean=85

The find standard deviation by using the standard deviation of a population formula as shown below.

16.07 is the standard deviation. Add 16.07 to the mean to get 101.07. Any numbers higher than this are ignored. Subtract 16.07 from the mean to get 68. 93. Any numbers lower that this are ignored. This means that all 6 scores are within one standard deviation of the mean.
