7.5, 8.2, 89, 9.3, 7.1, 8.3, 8.7. 9.5, 8.2, 9.1, 90, 90, 97, 92 89, 8.1, 90, 7.8, 8.0, 7.8, 7.0, 7.5, 13.5, 8.3, 6.8, 10.6, 8.3, 76, 77, 8.1

Let us now order the data values from smallest to largest.

6.8, 7.0, 7.1. 7.5, 7.5, 7.6, 77, 78, 7.8, 8.0, 8.1, 8.1, 82, 82, 83, 8.3, 8.3.

8.7, 8.9, 8.9, 90, 9.0, 9.0, 9.1, 92, 93, 9.5, 9.7, 10.6, 13.5

Make a vertical line.

Place the ones to the left of the vertical line and the tenths of each data value to the right of the vertical line

$\overline{)key:31}1means3.1$

We notice a gap between 13.5 and the remaining data values in the stemplot, indicating that 13.5 grams per 100 grams of cooked beans is a possible outlier.

As a results:

13.5 grams per 100 cooked beans is a possible outlier.

Then we notice that 7 of the 30 data values are greater than 9 (specifically, 9.1, 9.2, 9.3, 9.5, 9.7, 10.6, and 13.5).

$\frac{7}{30}鈮�0.2333$

This means that approximately 0.2333 of these bean varieties have more than 9 grams of protein per 100 grams of cooked beans.
