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: For Fertilizer A, the sample mean and sample variance are 464.9 and 1446.8. respectively. For Fertilizer B. the sample mean and sample variance are 423.8 and 766.8, respectively. Assume that the populations are approximately normal with unknown variances. What is the p-value for testing whether there is a difference in the mean yields for the two types of fertilizer? Use the a = 0.05 level of significance. O 0.01
