Question

data analysis and probability constructing a frequency distribution and a histogram (a) complete the grouped frequency distribution for the data. (note that the class width is 5.) number of miles frequency 1 to 5 6 to 10 11 to 15 16 to 20 (b) construct a histogram for frequency

Explanation:

Step1: Count data in 1 - 5

The numbers in the range 1 - 5 are 5, 4, 4, 4. So the frequency is 4.

Step2: Count data in 6 - 10

The numbers in the range 6 - 10 are 6, 5, 6, 7, 8, 10. So the frequency is 6.

Step3: Count data in 11 - 15

The numbers in the range 11 - 15 are 12, 13. So the frequency is 2.

Step4: Count data in 16 - 20

The numbers in the range 16 - 20 are 17, 16. So the frequency is 2.

Answer:

Number of miles	Frequency
6 to 10	6
11 to 15	2
16 to 20	2
