Fertilizer: In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Ten randomly selected plots of land were treated with fertilizer A, and 6 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 441 491 403 466 448 457 437 516 417 420 Fertilizer B 414 408 398 382 368 393 Send data to ExcelPart30f3 (c) Construct a 98% confidence interval for the difference between the mean yields for the two types of fertilizer. Let \"1 denote the mean yield for fertilizer A. Use tables to nd the critical value and round the answer to one decimal place. The 98% confidence interval for the difference between the mean yields for the two types of fertilizer is I
