Answer 1

Team A: 0

Team B: 0.3889

Team C: 0.5

Team D: 0.1111

Explanation:

The relative frequency is given by:

The division of the number of people in an interval by the total number of people.

In this question:

18 track members.

None ran between 0 and 4.9 seconds. So the frequency of Team A is 0/18 = 0

7 ran between 5 and 9.9 seconds. So the frequency of Team B is 7/18 = 0.3889

9 ran between 10 and 14.9 seconds. So the frequency of Team C is 9/18 = 0.5

2 ran between 15 and 19.2 seconds. So the frequency of Team D is 2/18 = 0.1111
