7 98% myleoonline.tamuc.edu In this exercise you will conduct five t tests (one for each cultivar; and one overall, meaning regardless of the cultivars). Table 2 below summarizes yield in 2011 (rather than in 2012). Use Tables 1 and 2 to test the hypothesis that wheat yield changed. That is, test the hypothesis that wheat yield is different from the yield levels specified in Table 2 below. In each of the five t tests: a. State the null and alternative hypotheses for the population mean in words. (Points: 3 b . State the null and alternative hypotheses for the population mean using the mathematical notation. (Points: 3) C Type the formula. Make sure you provide the formula in each t test. (Points: 1) d. Type the procedure. (Points: 4) e . Type the final answer. (Points: 3) f . Type the critical value(s). Use a = 0.05 significance level. (Points: 1) State the correct conclusion ("There is sufficient evidence at the a = 0.05 significance level to support..." or "There is NOT sufficient evidence at the a = 0.05 significance level to support..."). Make sure you state the conclusion in terms of H. (Points: 3) Table 2. Yield per cultivar, averaged across locations and treatments in 2011. Wheat Yield in 2011 Mean Itivar (kg/ha)
