Easy# Drawing Conclusions: Smokers

APSTAT-EMWAK2

A researcher decided to analyze the weights of smokers and non-smokers.

Suppose a random sample of $100\text{ smokers}$ averages $196.4\text{ lbs}$ with a standard deviation of $6.5\text{ lbs}$, and a random sample of $100\text{ non-smokers}$ averages $174.5\text{ lbs}$ with a standard deviation of $4.6\text{ lbs}$.

What conclusions could be drawn when comparing smokers to non-smokers?
