Question

A movie theater conducted a survey of its customers. Twelve people were selected at random and asked how many times they had gone to a movie theater in the past month. The movie theater recorded the results.
1, 4, 2, 7, 3, 11, 3, 5, 1, 1, 1, 3

What was the estimated mean number of movies a customer has seen?

A. 1
B. 3
C. 3.5
D. 4.3

Answer 1

Here, you know that 12 people answered.

Therefore :

Take the "M" for mean :

$M= \frac{1+4+2+7+3+11+3+5+1+1+1+3}{12}$
$M= \frac{42}{12}$
$M = 3.5$

In short, you answer would be C. 3.5.

Hope this helps !
