Question

reading a histogram
time spent practicing
the histogram represents the number of hours band students practice their instruments. use the drop - down menus to complete the statements.
the bars represent drop - down menu.
according to the histogram, drop - down menu students spend 3 or more hours practicing.
according to the histogram, drop - down menu students spend fewer than 2 hours practicing.
(the histogram has a y - axis labeled students with values 0, 2, 4, 6, 8, 10, 12, 14 and an x - axis labeled hours with intervals 0 - 0.59, 1 - 1.59, 2 - 2.59, 3 - 3.59, 4 - 4.59. the bars have heights corresponding to the number of students in each hour interval.)

Explanation:

Step1: Understand the histogram concept

In a histogram, the bars represent the frequency (number of students in this case) for each class interval (hours of practice).

Step2: Calculate students spending 3 or more hours

The class intervals for 3 - 3.59 hours and 4 - 4.59 hours. The number of students in 3 - 3.59 hours is 3 and in 4 - 4.59 hours is 1. So total is \(3 + 1=4\).

Step3: Calculate students spending fewer than 2 hours

The class interval is 0 - 0.59 hours. The number of students is 3.

Answer:

The bars represent the number of students.
According to the histogram, 4 students spend 3 or more hours practicing.
According to the histogram, 3 students spend fewer than 2 hours practicing.
