Agriculture: Wheat Rothamsted Experimental Station
Chapter , Problem 6(choose chapter or problem)
Agriculture: Wheat Two plots at Rothamsted Experimental Station (see reference in Problem 5) were studied for production of wheat straw. For a random sample of years, the annual wheat straw production (in pounds) from one plot was as follows:
Use a calculator to verify that, for the preceding data, \(s^2 \approx 0.318\).
Another random sample of years for a second plot gave the following annual wheat straw production (in pounds):
Use a calculator to verify that, for these data, \(s^2 \approx 1.078\).
Test the claim that there is a difference (either way) in the population variance of wheat straw production for these two plots. Use a 5% level of significance.
