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 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 445 523 464 483 441 491 403 466 437 457
Fertilizer B 362 414 408 398 385 368 390 437
Construct a 95% confidence interval for the difference
between the mean yields for the two types of fertilizer.
Let μ1 denote the mean yield for fertilizer A. Use the
TI-84 Plus calculator. Round the answers to one decimal place
The 95% confidence interval for the difference between
the mean yields for the two types of fertilizer is <
μ1- μ2 <
