Question

question 10 of 10 > the dotplot shows the epa highway gas mileage estimates in miles per gallon (mpg) for a sample of 21 model year 2020 midsize cars. explain why this distribution of highway gas mileage is not approximately normal. the distribution of highway gas mileage is not approximately normal because the distribution is skewed to the right. the distribution of highway gas mileage is not approximately normal because there appears to be an outlier. the distribution of highway gas mileage is not approximately normal because the distribution is skewed to the left. the distribution of highway gas mileage is not approximately normal because there is too much variability.

Explanation:

A normal distribution is symmetric. Looking at the dot - plot, the majority of the data is clustered on the left side (around 30 mpg), with a long tail extending to the right. This indicates right - skewness. A normal distribution does not have such skewness.

Answer:

The distribution of highway gas mileage is not approximately normal because the distribution is skewed to the right.
