Rothamsted experimental station (england) has studied wheat production since 1852. each year many small plots of equal size but different soil/fertilizer conditions are planted with wheat. at the end of the growing season, the yield (in pounds) of the wheat on the plot is measured. suppose for a random sample of years, one plot gave the following annual wheat production (in pounds): 2.98 1.60 2.30 4.27 4.09 3.81 3.56 4.32 2.34 2.82 2.30 3.89 1.65 4.43 2.47 4.09 use a calculator to verify that the sample variance for this plot is . another random sample of years for a second plot gave the following annual wheat production (in pounds): 3.84 1.50 3.85 4.27 3.23 3.04 3.43 2.15 3.58 2.92 1.68 3.14 2.88 3.05 1.94 3.06 use a calculator to verify that the sample variance for this plot is . and verify that that p-value > 0.1. test the claim using that the population variance of annual wheat production for the first plot is larger than that for the second plot. will you reject or fail to reject the null hypothesis?
