The data below represent the top speed (in kilometers per hour) of all the players (except goaltenders) in a certain soccer league.

Number of Players 5 Speed (km/hr) 10-13.9 14-17.9 18-21.9 22-25.9 26-29.9 30-33.9 16 80 259

Find (a) the number of classes, (b) the class limits for the third class, and (c) the class width

a. 6

b. 18-21.9

c. 4

Step-by-step explanation:

a)

The number of classes can be assessed by counting the number of class intervals

S. no Class interval

1 10-13.9

2 14-17.9

3 18-21.9

4 22-25.9

5 26-29.9

6 30-33.9

Hence, there are 6 number of classes

b)

The class limits for third class is 18-21.9.

Upper class limit = 18

Lower class limit=21.9

c)

The class width can be calculated by taking difference of two consecutive upper class limits or two consecutive lower class limits.

Class width=14-10=4
