In Diabetes management ,an important treatment goal is to lower hemoglobin A1c,.Suppose we wanted to test the hypothesis that Drug A is more effective than Drug B in lowing the A1c level.healthy people who do not have diabetes have an A1c bet. 4 and 5 The goal in diabetes management is often to reduce the patient's A1c.

Using the following information ,compute t-statistic for independent groups.


A1c level after 3 mos. of treatment

mean with Drug A= 7.7

mean with Drug B = 7.5


each group has n= 30

SD1= .8

SD2= .7

What are the degrees of freedom and the value of t ? Using alpha =0.05 for a two tailed test, is this t statistic significant?
