Match the histogram on the left to the normal probability pl

Match the histogram on the left to the normal probability plot on the right.

A. Normal Probability Plot 15 10 Data Normal Probability Plot B. 35 30 25 20 15 10 1 2 3 456 78 9 10 1 23 45 7 9 10 Data

Solution

The first histogram appears normally distributed, so the normal probability plot is a straight line, as in D.

The second histogram appears skewed to the left, so the normal probability plot is bending towards the end, as in B.

The third histogram appears skewed to the right, so the normal probability plot is rising towards the end, as in A.

The fourth histogram appears skewed to the centre, so the normal probability plot is steep on both ends, as in C.
