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?
Added by Dennis H.
Step 1
- The null hypothesis (H0) states that there is no difference in the crop yield between the traditional and the new fertilizer, meaning the mean yield with the new fertilizer is equal to 20 tonnes per acre. - The alternative hypothesis (H1) states that the new Show more…

In an agricultural study, the average amount of corn yield is normally distributed with a mean of 185.2 bushels of corn per acre, with a standard deviation of 23.5 bushels of corn. If a study included 1100 acres, about how many would be expected to yield more than 190 bushels of corn per acre?

Increasing corn yield. A large farm wants to try out a new type of fertilizer to evaluate whether it will improve the farm's corn production. The land is broken into plots that produce an average of 1,215 pounds of corn with a standard deviation of 94 pounds per plot. The owner is interested in detecting any average difference of at least 40 pounds per plot. How many plots of land would be needed for the experiment if the desired power level is 90%? Assume each plot of land gets treated with either the current fertilizer or the new fertilizer.

A farmer wishes to test the effectiveness of a new kind of fertilizer. He plants his crops on 24 plots of equal size. Design an experiment he can use to test the new fertilizer. (Be sure to explain how randomness will be used.)
