The makers of a new chemical fertilizer claim that the yields will average 0.40 tons more per acre if this fertilizer is used than if the leading brand is used. The agricultural testing service has tested this claim. A random sample of 52 acre-sized plots was selected and the new fertilizer was applied. A second sample of 40 acre-sized plots was selected and the leading fertilizer was used. The following sample data (in tons per acre) were observed: Current Leading Brand: 4.0 tons/acre New Product: 5.2 tons/acre If α = 0.05, what conclusion should be reached with respect to the claim made by the new fertilizer's company? Discuss.

An agricultural researcher claims that a new fertilizer increases the average yield of a certain crop to more than 200 bushels per acre. A field test is conducted on 50 randomly chosen plots using the new fertilizer, resulting in an average yield of 205 bushels per acre with a standard deviation of 10 bushels. Conduct a hypothesis test at a 2.5% significance level to assess the effectiveness of the new fertilizer.

A farming company wants to test if a new fertilizer will improve crop yield or not. The average yield of crop using the traditional fertilizer of the farm is 20 tonne per acre. They decide to test the new fertilizer on 12 different farms, and get the average yield of the crop of 21 tonne per acre with a standard deviation of 3 tonne per acre. Did the new fertilizer work?
