On the six tests in her social studies course, Jerelyn's score were 92, 78, 86, 92, 95, and 91. Determine the median and the mode of her scores. If Jerelyn took a seventh test and raised the mean of her scores exactly 1 point, what was her score on the seventh test?
.......I has posted this question few days back. From the help that I got form this website i could find out the mode and median. But the problem that i am having is :

My question is:
On the six tests in her social studies course, Jerelyn's score were 92, 78, 86, 92, 95, and 91. Determine the median and the mode of her scores. If Jerelyn took a seventh test and raised the mean of her scores exactly 1 point, what was her score on the seventh test?

the mode is 92, and the median is 91. the answer for the 3rd question is 96 like u thought. the mean of the 6 tests is 89. you needed to add a point so i did. which was 90. i multiplied that by 7 because now there are 7 tests. the product was 630. i subtracted 534 from 630 to get 96 which is the answer
