There are 20 plants in the control plot with mean seed number 15.0, and the variance for seed number in both populations is known to be 25.0. Compare with the results in Section 8.5, Exercise 4.
Recall the data in Section 8.5, Exercises 1-4 describing 10 plants in an experimental plot.

Suppose that these plants are being compared with populations in a control plot. Use a two-tailed test, and compare the p-values with those found in the earlier problem.
