Question

nine cyclists were each asked the distance in miles they biked last week.
their responses are given below.
complete the grouped frequency distribution for the data.
in the distribution, the frequency of a class is the number of distances in that class.
(note that we are using a class width of 6.)

distance in miles:
10, 18, 7
4, 4, 4
11, 11, 9

distance in miles | frequency
2 to 7 |
8 to 13 |
14 to 19 |

Explanation:

Sort the raw data

$$ \{4, 4, 4, 7, 9, 10, 11, 11, 18\} $$

Count frequencies for each class interval

$$
LATEXBLOCK0
$$

Verify total count

$$ 4 + 4 + 1 = 9 $$

Answer:

Distance in miles	Frequency
8 to 13	4
14 to 19	1
