he data to the right represent the top speed (in kilometers per hour) of all the players (except goaltenders) in a certain so
ccer league. Construct (a) a relative frequency distribution (b) a frequency histogram, and (c) a relative frequency histogram. What percentage of players had a top speed between 14 and 17.9 km/h? What percentage of players had a top speed less than 13.9 km/h?
1 answer:
Answer:
a)
0.3212
b)
The percentage of player that had a top speed less than 13.9 km/h = 0.007259 x 100 = 0.7259%
Step-by-step explanation:
a) Construct relative frequency distribution?
Speed (km/hour) Number of players Relative frequency
10 – 13.9
14-17.9
18 – 21.9
22 – 25.9
26 – 29.9
30 – 33.9

177 4/551=0.007259
8/551=0.01451
18/551=0.03266
76/ 551=0.1379
268/551 = 0.486
177/551=0.3212
(b) frequency histogram:

The percentage of player had top speed between 14 and 17.9 km/h was = 0.01451 x100 = 1.451%
The percentage of player that had a top speed less than 13.9 km/h = 0.007259 x 100 = 0.7259%
