the best regression equation for predicting the amount of nicotine in a cigarette.
A. Nicotine = __ + (__) Tar + (__) CO is the correct choice of predicting the variables
Nicotine = 0.255+0.082 Tar - 0.028 CO
Multiple linear regression is one of the best satistica; anlysis to predict the vatiables.

Refer to the accompanying data table, which shows the amounts
of nicotine (mg per cigarette) in king-size cigarettes, 100-mm
menthol cigarettes, and 100-mm nonmenthol cigarettes. The
king-size cigarettes are nonfiltered, while the 100-mm menthol
cigarettes and the 100-mm nonmenthol cigarettes are filtered. Use
a 0.05 significance level to test the claim that the three
categories of cigarettes yield the same mean amount of nicotine.
Given that only the king-size cigarettes are not filtered, do the
filters appear to make a...
