Question

A study was condacted that resulited in the tolowing relative frequency hstogram Determine whether or not the hstogram indicates that a noal bution could be used as a model for the variable Choose the correct anower below O A. The histogram is not bell-shaped, so a noma dstribution could be used as a model for the variable O B. The histogram is bell shaped, so a normal distibution could be used as a model for the vaniable O C.

Explanation / Answer

The histogram is right skewed. Thus it represents positively skewed distribution and not bell shaped distribution.

Thus we cannot use normal distribution as a model.

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