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.

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