Question

a study was conducted that resulted in the following relative frequency histogram determine whether or not the histogram indicates that a normal distribution could be used as a model for the variable
choose the correct answer below
a. the histogram is not bell - shaped, so a normal distribution could be used as a model for the variable
b. the histogram is bell - shaped, so a normal distribution could not be used as a model for the variable
c. the histogram is not bell - shaped, so a normal distribution could not be used as a model for the variable
d. the histogram is bell - shaped, so a normal distribution could be used as a model for the variable

Explanation:

A normal distribution has a bell - shaped histogram. Looking at the given histogram, it is not bell - shaped. Since a normal distribution model requires a bell - shaped histogram, if the histogram is not bell - shaped, a normal distribution cannot be used as a model for the variable.

Answer:

C. The histogram is not bell - shaped, so a normal distribution could not be used as a model for the variable.
