n 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 473 507 526 479 477 468 516 467 519 523 483 540 518 488 Fertilizer B 455 501 470 420 483 419 468 476 459 513 Assume that the populations are approximately normal. Construct a 95% confidence interval for the difference between the mean yields for the two types of fertilizer. Interpret the results.
