A study was conducted to determine the efficacy of an oral antidiabetic drug. Patients were given a single dose of either 1 mg or 2 mg of the drug, and the maximum plasma concentration of the drug (in ng/ml) was assessed. The results are as follows:

Treatment	sample size	mean	standard deviation
1 mg	32	3.16	0.72
2 mg	32	3.15	0.69

To determine if maximum plasma concentration is dose dependent, construct a hypothesis test (pooled) for the difference in means maximum plasma concentration of the drug. Test at 5% level of significance.(Show your work for full credits, make sure to state your hypotheses, test statistic, p value, and conclusion.)
