The data below are for two different types of straw seed that were used on adjacent plots of land. The listed values are the yields of straw in cwt (100 lb, or hundredweight) per acre, and the yields are paired by the plot of land that they share. Complete parts (a) through (c) Type 1 19.5 22.75 23 23 25 22.25 1975 24.26 15.75 18.25 14.5 17 Type 2 24.75 24 24 27 75 22.75 195 22.5 15.75 17 15.5 17.25 a. Using a 0.05 significance level, test the claim that there is no difference between the yields from the two types of seed. Let , be the mean of the population of differences of type 1 minus type 2 and write the hypotheses The null hypothesis is Hy: Ha = 0. The alternative hypothesis is H.: 30 The test statistic is (Round to two decimal places as needed. )
