a. Give a simple linear regression model that fits Y (drug amount) as a
b. Give a ANOVA table testing for the significance of the model you found and for testing for goodness of fit at a=0.05
c. Provide a 95% confidence interval for the slope of the linear regression model and determine if it is not zero.
