Question

Find the confidence interval and write interpretation for each problem.

3) 3) Construct the confidence interval for the difference pl-P2 for the given level and values of x1,1, x2, and n2. Level 98%: xy - 27, n, - 64, X2 = 16, 12 - 55 4) 4) 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. Followin are the results. Fertilizer A 473 507 526 479 477 468 516 467 519 523 483 540 518 488 Fertilizer B 455 501 470 420 483 419 468 476 459 413 Assume that the populations are approximately normal. Construct a 95% confide interval for the difference between the mean yields for the two types of fertilizer.
