C) Construct an 80% confidence interval for the difference between the mean yields for the two types of fertilizer. Let u1 denote the mean yield for fertilizer A. Use tables to find the critical value and round the answer to one decimal place. The 80% confidence interval for the difference between the mean yields for the two types of fertilizer is_

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 9 randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot.
