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

Answer:

13.3

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:

$\begin{gathered} \text{Mean}=\frac{7+12+12+16+13+19+14}{7} \\ =\frac{93}{7} \\ =13.3 \end{gathered}$

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