1.In an agricultural experiment, two expensive high-yield varieties of corn are to be tested and the yield improvements are measured. The experiment is arranged so that each variety is planted in one of each of ten pairs of similar plots. The data shown in the accompanying table are the percentage yield increases obtained for these two varieties. You need to sate the assumption if needed. Test at the 0.10 percent significance level the null hypothesis that the two population mean percentage yield increases are the same against two sided alternative hypotheses, and interpret the result.
