I need help approaching this question for coker 9553

Table 1. Yield response to fungicide applications per cultivar, averaged across locations and treatments in 2012. Yield (kg/ha) Cultivar n Mean Std. Dev. 36 6215.04 590.8006 Coker 9553 5403.00 567.2484 Terral LA841 36 5619.46 Magnolia 678.7984 36 Pioneer 25R47 5763.93 900.3796 36 Overall 36 5750.36 684.31 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 the yield response to fungicide application 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. -.of b. State the null and alternative hypotheses for the population mean using the mathematical notation.- Type the formula. Make sure you provide the formula in each / test. {} Type the procedure. Type the final answer. Points Type the critical value(s). Use a = 0.05 significance level. #Pointset) 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 HI. Table 2. Yield response to fungicide applications per cultivar, averaged across locations and treatments in 2011.
