Answer:
65.
Step-by-step explanation:
We have been given the scores received by Linda on her essay tests and we are asked to find the mean of Linda's scores.
The score are: 64, 65, 63, 66, 60, 65, 66, 68, 69, 66, 63.
To find the mean of her scores we will add all the scores and divide by the number of tests.
[tex]\text{Mean of Linda's scores}=\frac{64+65+63+66+60+65+66+68+69+66+63}{11}[/tex]
[tex]\text{Mean of Linda's scores}=\frac{715}{11}[/tex]
[tex]\text{Mean of Linda's scores}=65[/tex]
Therefore, the mean of Linda's scores is 65.
