21, 23, 4, 23, 20, 17, 20, 0, 11, 20, 11, 13, 17, 2, 13, 3, 5, 10, 13, 14, 15, 21, 5, 5, 1, 17, 14, 3, 2, 17, 8
*click the tally box to count up. the minus counts down.
interval tally frequency
0 - 4 6
5 - 9 4
10 - 14 8
15 - 19 5
20 - 24 6

Explanation:

Step1: Identify the task

The task is to verify the frequencies in the frequency - table for the given data set.

Step2: Count the data points in each interval

• For the interval \(0 - 4\): The numbers \(4,0,2,3,3,2\) fall in this interval. Counting them, we get 6.
• For the interval \(5 - 9\): The numbers \(5,5,5,8\) fall in this interval. Counting them, we get 4.
• For the interval \(10 - 14\): The numbers \(11,11,13,13,10,13,14,14\) fall in this interval. Counting them, we get 8.
• For the interval \(15 - 19\): The numbers \(17,17,15,17,17\) fall in this interval. Counting them, we get 5.
• For the interval \(20 - 24\): The numbers \(21,23,23,20,20,21\) fall in this interval. Counting them, we get 6.

Answer:

The frequencies in the table are correct.
