Question

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:

$$ 	ext{A}: 150, \,  155, \,  160, \,  165, \,  170, \,  180, \,  190$$


$$ 	ext{B}: 140, \,  145, \,  150, \,  155, \,  160, \,  165, \,  170$$

What can be inferred about the effectiveness of the medications in lowering blood sugar based on the means of these two groups?

Accepted Answer

Group B’s medication appears more effective in reducing blood sugar.

Answer

Both medications are equally effective.

Answer
