Two plots at Rothamsted Experimental Station 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.7.036.475.916.127.317.187.065.796.245.916.14Use a calculator to verify that, for this plot, the sample variance iss²0.325.

Another random sample of years for a second plot gave the following annual wheat production (in pounds).6.686.267.317.317.225.585.475.86Use a calculator to verify that the sample variance for this plot iss²0.604.

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 signifcance.
