A doctor was interested in determining how the amount of drug consumed by a patient affected the patient's reaction time. There were n=4 patients in the study. Below is the Minitab ouput. Find a 95% CI for the slope.

The regression equation is Reaction Time = - 0.100 + 0.700 Amount of Drug

Predictor	Coef	SE coef	T	p-value
Constant	-0.100	0.6351	-0.16	0.885
Amount of Drug	0.700	0.1915	3.66	0.035
