Question

A group of 6 students was asked how many hours did you watch television last week?' Here are there responses. 5,5,5,7,16,11 Find the mean number of hours for these students If necessary, round your answer to the nearest tenth.

Answer 1

Answer: The mean number of hours is 8.2

Step-by-step explanation: The observed data has been given as follows;

5,5,5,7,15,11.

The mean of the set of data can be derived as follows;

Mean = ∑x ÷ f

Where ∑x is the addition of all observed data and f is the number of data observed.

Mean = (5 + 5 + 5 + 7 + 16 + 11)/6

Mean = 49/6

Mean = 8.1667

Therefore the mean number of hours to the nearest tenth is 8.2 hours
