Question

a survey was given to 87 students at a local high school, asking how many minutes it takes them to commute to school. the results are summarized in the table below. construct and label a frequency histogram of the data with an appropriate scale.

minutes	num. of students
20 - 39	36
40 - 59	6
60 - 79	3

click and drag to make a rectangle. click a rectangle to delete it.

Explanation:

Step1: Set up x - axis

Label the x - axis as "Minutes to Commute" and mark the intervals 0 - 19, 20 - 39, 40 - 59, 60 - 79.

Step2: Set up y - axis

Label the y - axis as "Frequency (Number of Students)". Since the highest frequency is 42, a good scale could be 0, 5, 10, 15, 20, 25, 30, 35, 40, 45.

Step3: Draw rectangles

For the interval 0 - 19, draw a rectangle with height 42. For the interval 20 - 39, draw a rectangle with height 36. For the interval 40 - 59, draw a rectangle with height 6. For the interval 60 - 79, draw a rectangle with height 3.

Answer:

A frequency histogram with x - axis labeled "Minutes to Commute" having intervals 0 - 19, 20 - 39, 40 - 59, 60 - 79 and y - axis labeled "Frequency (Number of Students)" with scale 0, 5, 10, 15, 20, 25, 30, 35, 40, 45 and rectangles of heights 42, 36, 6, 3 respectively for the given intervals.
