Answer 1

Relative Frequency:

0 movies: 3/25 = 0.12

1 movie: 9/25 = 0.36

2 movies: 8/25 = 0.32

3 movies: 4/25 = 0.16

4 movies: 1/25 = 0.04

Cumulative Relative Frequency:

0 movies: 3/25 = 0.12

1 movie: (3/25) + (9/25) = 12/25 = 0.48

2 movies: (12/25) + (8/25) = 20/25 = 0.80

3 movies: (20/25) + (4/25) = 24/25 = 0.96

4 movies: (24/25) + (1/25) = 25/25 = 1.00
