Expert Solution
Step 1

Null Hypothesis:

H0: There is no difference in the mean baseline blood glucose between control and glucose groups.

Alternative Hypothesis:

H1: There is a difference in the mean baseline blood glucose between control and glucose groups.

 

Given information:

Control group Glucose group
100 95
104 124
93 105
131 112
110 108
85 86
100 90
88 95
92
