Answer:
13.3
Explanation:
To calculate the mean number of movies, use the formula below:
[tex]\text{Mean}=\frac{\text{Sum of the number of movies seen}}{\text{Number of students}}[/tex]
Substituting the data gives:
[tex]\begin{gathered} \text{Mean}=\frac{7+12+12+16+13+19+14}{7} \\ =\frac{93}{7} \\ =13.3 \end{gathered}[/tex]
The mean number of movies that the students saw is 13.3 (correct to the nearest tenth).
