There are 15 plants in the control plot with mean yield 8.2, and the variance for yield in both populations is known to be 6.25. Compare with the results in Section 8.5, Exercise 3.
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.

Plant Weight Height Yield Number of seeds 11.83 7.65 14.57 14.97 46.2 10.11 9.29 414 12.26 6.61 14.26 38.5 9.51 8.34 39.8 13.35 7.04 37.9 12.90 34.8 10.35 9.84 39.4 18 40.8 16 17 11.26 11.08 40.7 21 5.44 20 10 11.82 43.1
