Question 22 - Math Practice Test for the NLN NEX

A nurse compares two medications used to reduce blood sugar levels in diabetic patients. The fasting blood sugar levels (in mg/dL) of two groups of patients, each receiving a different medication, are recorded after one week of treatment. The data for Group A and Group B are as follows:

\[\text{A}: 150, \, 155, \, 160, \, 165, \, 170, \, 180, \, 190\] \[\text{B}: 140, \, 145, \, 150, \, 155, \, 160, \, 165, \, 170\]

What can be inferred about the effectiveness of the medications in lowering blood sugar based on the means of these two groups?
