Question

Normal probability plots for three data sets are shown on the next page. Which plot indicates that the data are approximately normally distributed?

Short answer

The plot in part-(c) indicates that data is normally distributed.

Step-by-step solution

Given Information

Explanation

In the first plot (i.e,part-(a))if we draw a straight line then maximum data points fall below the straight line, so the data is not normally distributed.

In the second plot (i.e,part-(b))if we draw a straight line then maximum data points fall above the straight line, so the data is not normally distributed.

In the third plot (i.e, part-(c) if we draw a straight line then maximum data points fall on the straight line, so the data is normally distributed.
