(t Test (in Excel) for Two Samples with Unequal Variances) In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Fourteen randomly selected plots of land were treated with fertilizer A, and 10 randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot. Following are the results. Fertilizer A Fertilizer B 448, 478,482, 442,455, 480 ,457, 506, 436,478,453,489,400,444,495,438,481,501 470,444, 466, 427, 461, 431 Assume that the populations are approximately normal. Can you conclude that there is a difference in the mean yields for the two types of fertilizer? Use the α = 0.01 level of significance. Use Excel to perform the hypothesis test. State the null and alternate hypotheses that would be appropriate for this hypothesis…
