Final answer:
The mean number of movies that the students saw is 13.
Step-by-step explanation:
To find the mean (average) number of movies that the students saw, you need to add up all the numbers and then divide the sum by the total number of values. In this case, the given numbers are 19, 14, 8, 9, and 14.
Step 1: Add all the numbers together: 19 + 14 + 8 + 9 + 14 = 64.
Step 2: Divide the sum by the total number of values (in this case, 5): 64 ÷ 5 = 12.8.
Therefore, the mean number of movies that the students saw is 12.8 (rounded to the nearest whole number, which is 13).
