In an agricultural experiment, the effects of two fertilizers on the production of limes were measured. Thirty-eight randomly selected plots of land were treated with a brand new fertilizer, and 35 randomly selected plots were treated with an old fertlizer. The number of pounds of harvested limes were measured from each plot. The results are given below (Round answers to two decimal places.)

Yes, we are 97% confident that new fertilizer is better than old fertilizer. It's not clear if the new fertilizer is better than the old fertilizer. No, we are 97% confident that new fertilizer is not better than old fertilizer
