Reference no: EM13965402

In order to compare the mean Hemoglobin (Hb) levels of well-nourished and undernourished groups of children, random samples from each of these groups yielded the following summary.

	Number of children	Sample mean	Sample standard deviation
Well nourished	95	11.2	0.9
Undernourished	75	9.8	1.2

Test at α = 0.01 whether the mean Hb levels of well-nourished children were higher than those of undernourished children.
