Each of 6 students reported the number of movies they saw in the past year. Here is what they reported. 10,15,13,15,16,20 Find the mean number of movies that the students saw. If necessary, round your answer to the nearest tenth.

Answer 1

The mean is the average.

Add all the movies that the students saw:

 

10+15+13+15+16+20=89 movies

 

Divide the total movies by the number of students

 

89/6=14.83

 

Round to the nearest tenth =14.8
