Question

Each of students reported the number of movies they saw in the past year. Here is what they reported.

12,17,8,13,5,18
Find the mean number of movies that the students saw.
If necessary, round your answer to the nearest tenth.

Answer 1

12.2

Explanation:

The mean is the average, so we add up the number of movies, and divide by 6 beacause they are reported by 6 students

Mean (Average) = (12+17+8+13+5+18) / 6

Mean (Average) = 73 / 6

Mean (Average) = 12.16666667

The problem asks us to round to the nearest tenth, which is the first decimal place.

Since the 2nd decimal place, 6, is more than 5, we round the first decimal place up to one and remove the rest.

12.2

Answer 2

10,20,10,10,10,20 tenths
