**Answer:**

**C and E are correct**

**Step-by-step explanation:**

We have to calculate mean , median and mode for both groups first:

So,

For the group that studied:

Mean = 92.61

Median=93.5

Mode = 100

For the group that didn't studied:

Mean = 76

Median = 79.5

Mode = No Mode

So,

For statement A:

the difference between means is: 92.61-76=16.61

So the statement is incorrect.

B: There is no mode of the group that studied.

This is not true as the group has a mode of 100

**C.The median of the group that did not study is less than 80.**

**This is true as the median of the group that didn't study is 79.5.**

D. The median of the group that studied is over 95

False as the median is less than 95.

**E. In general, those students that studied scored much higher than those students that did not study.**

**As the mean of the group that studied is much more than the group that didn't study so the statement is true ..**
