Answer:
12.2
Step-by-step 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
