Question

Each of 7 students reported the number of movies they saw in the past year. Here is what they reported. 7,12,12,16,13,19,14.

Answer 1

13.3

Step-by-step explanation:

To calculate the mean number of movies, use the formula below:

`\text{Mean}=\frac{\text{Sum of the number of movies seen}}{\text{Number of students}}`

Substituting the data gives:

`\begin{gathered} \text{Mean}=(7+12+12+16+13+19+14)/(7) \\ =(93)/(7) \\ =13.3 \end{gathered}`

The mean number of movies that the students saw is 13.3 (correct to the nearest tenth).
