the data to the right represent the top speed (in kilometers per hour) of all the players (except goalkeepers) in a certain soccer league. find (a) the number of classes, (b) the class limits for the fourth class, and (c) the class width.\n(a) there are classes. (type a whole number.)

Answer

Explanation:

Step1: Count number of classes

Count the number of speed - intervals in the table. There are 6 intervals: 10 - 13.9, 14 - 17.9, 18 - 21.9, 22 - 25.9, 26 - 29.9, 30 - 33.9.

Step2: Identify fourth - class limits

The fourth class is 22 - 25.9. The lower limit is 22 and the upper limit is 25.9.

Step3: Calculate class width

Take the difference between the lower limit of a class and the lower limit of the next class. For example, for the first two classes, the lower limit of the first class is 10 and the lower limit of the second class is 14. The class width is $14 - 10=4$.

Answer:

(a) 6 (b) Lower limit: 22, Upper limit: 25.9 (c) 4
