Answer 1

Mean number of hours watched: 12

Median number of hours watched: 13.5

Explanation:

To find the mean and median number of hours for the students, we'll use the following data:

12, 4, 19, 16, 7, 8, 15, 15

Mean:

To find the mean (average), we sum up all the numbers and divide the sum by the total count.

Sum = 12 + 4 + 19 + 16 + 7 + 8 + 15 + 15 = 96

Count = 8

Mean = Sum / Count = 96 / 8 = 12

Therefore, the mean number of hours watched is 12.

Median:

To find the median, we arrange the numbers in ascending order and determine the middle value.

Arranged in ascending order: 4, 7, 8, 12, 15, 15, 16, 19

Since we have 8 values, the median will be the average of the two middle values, which are 12 and 15.

Median = (12 + 15) / 2 = 27 / 2 = 13.5

Therefore, the median number of hours watched is 13.5 (rounded to the nearest tenth).

Answer 2

To find the mean and median number of hours watched by the students, we'll first arrange the responses in ascending order:

4, 7, 8, 12, 15, 15, 16, 19

Mean:
The mean is calculated by finding the sum of all the values and then dividing by the total number of values. In this case, we have 8 values:

Mean = (4 + 7 + 8 + 12 + 15 + 15 + 16 + 19) / 8 = 96 / 8 = 12

Therefore, the mean number of hours watched by the students is 12 hours.

Median:
The median is the middle value in a set of numbers when arranged in ascending or descending order. Since we have 8 values, the median is the average of the two middle values.

The two middle values are 12 and 15. So, the median is (12 + 15) / 2 = 27 / 2 = 13.5

Therefore, the median number of hours watched by the students is 13.5 hours (rounded to the nearest tenth).

The mean is 12 hours and the median is 13.5 hours.
