Question
Are yields for organic farming different from conventional farming yields? Independent random samples from method A (organic farming) and method B (conventional farming) gave the following information about yield of lima beans (in tons/acre).
Method A | 1.85 | 1.27 | 1.15 | 1.23 | 1.53 | 1.51 | 1.71 | 1.87 | 1.37 | 1.99 | 2.33 | |
---|---|---|---|---|---|---|---|---|---|---|---|---|
Method B | 1.13 | 1.29 | 1.77 | 1.61 | 2.01 | 1.43 | 1.93 | 1.35 | 1.63 | 1.89 | 1.83 | 2.17 |
Use a 5% level of significance to test the hypothesis that there is no difference between the yield distributions.
(a) What is the level of significance?
(b) Compute the sample test statistic. (Use 2 decimal places.)
(c) Find the P-value of the sample test statistic (Use 4 decimal places.)
