eighteen cyclists were each asked the number of miles they biked last week. their responses are given below…

Explanation:

Step1: Identify task

We are given data on miles biked and need to analyze it.

Step2: Check grouped - frequency distribution

Count the number of data - points in each class interval. For 2 to 7: The values 3, 5, 4, 2, 6, 5, 3, 4, 2, 6, 5 fall in this range. Counting them gives a frequency of 11. For 8 to 13: The values 10, 11, 9, 9 fall in this range. Counting them gives a frequency of 4. For 14 to 19: The values 19, 18 fall in this range. Counting them gives a frequency of 2. For 20 to 25: The values 24, 24, 22 fall in this range. Counting them gives a frequency of 3.

Step3: Histogram construction

The x - axis represents the class intervals (2 to 7, 8 to 13, 14 to 19, 20 to 25) and the y - axis represents the frequency. The height of the bar for the interval 2 to 7 is 11, for 8 to 13 is 4, for 14 to 19 is 2 and for 20 to 25 is 3.

Answer:

The grouped - frequency distribution and histogram are already correctly completed as shown in the problem statement. The frequency distribution:

Number of miles	Frequency
2 to 7	11
8 to 13	4
14 to 19	2
20 to 25	3
The histogram has bars with heights corresponding to the frequencies for each class interval.
