Question
Clearly state the null and alternative hypothesis and your assumptions.
The percent reduction in blood sugar a certain time after injection of insulin into rabbits is given below. A group of 24 rabbits was divided at random into six groups of four rabbits each, and each rabbit received an injection of insulin. Two factors were involved, the dose at three levels and the preparation of insulin in two ways, A and B. Analyze this using a two-way analysis of variance for a factorial design (repeated measurements). (10 points).
Dose Level__________
Preparation I ii iii
A 17 64 62
21 49 72
49 34 61
54 63 91
B 33 41 56
37 64 62
40 34 57
16 64 72
Explanation / Answer
following information has been generated, using the given data
here only dose is found significant at 5% level of significance and preparation(prep) and internaction between
prepartion and dose (prep*dose) are not significant at 5% level of significance.
