Question

(a) what is the class width? (b) one class is the most frequent. how many teams are in this class? (c) according to the histogram, what is the total number of teams?

Explanation:

Step1: Calculate class width

Class width is the difference between upper and lower class limits. For the first class \(210 - 284\), \(284 - 210=74\).

Step2: Find the most - frequent class

The tallest bar in the histogram represents the most - frequent class. The bar for the class \(210 - 284\) has a height of \(9\).

Step3: Calculate total number of teams

Sum the frequencies of all classes. \(9 + 4+2 + 4=19\)

Answer:

(a) \(74\)
(b) \(9\)
(c) \(19\)
