Question

a histogram for the number of semester credits hours for a sample of 100 general introductory statistics students is pictured below. choose the best description of the horizontal axis for the histogram. the number of semester credit hours. the mean number of semester credit hours for each bin. the number of students. the mean number of students for each bin.

Explanation:

In a histogram for semester credit hours of students, the horizontal axis (x - axis) represents the variable being measured, which is the number of semester credit hours. The vertical axis (y - axis) would represent the frequency (number of students) in each bin. The mean - related options are incorrect as histograms show distributions of individual values, not means of bins, and "number of students" is for the y - axis.

Answer:

A. The number of semester credit hours.
