Question

William Gosset published the article "The Probable Error of a Mean" under the pseudonym of "Student". He included matched-pair data for corn seed that was prepared using two different methods (regular & kiln dried). The data values are the yields of sampled harvested corn in pounds per acre.

Regular (sample set 1):	1492	1844	2350	1426	1888	2284	2108	2372
Kiln dried (sample set 2):	2240	2274	2036	2257	2189	1580	1496	1444

a) Use a 0.05 significance level to test the claim that there is no difference between the yields from the two methods.

Claim: d  ---Select--- < > = ≤ ≥ ≠ 0

Ho: d    ---Select--- < > = ≤ ≥ ≠ 0

H1: d    ---Select--- < > = ≠ ≤ ≥ 0

b) What was the rejection result? Does it appear that either method of seed preparation is better?

Reject the null hypothesis. There is not significant evidence that one seed preparation method yields better than the other.Do not reject the null hypothesis. There is significant evidence that one seed preparation method yields better than the other.    Do not reject the null hypothesis. There is not significant evidence that one seed preparation method yields better than the other.Reject the null hypothesis. There is significant evidence that one seed preparation method yields better than the other.
