# Question

Following are the data on plant weight and quantity of volatile emissions from Exercise 14.19.
a. Obtain a point estimate for the mean quantity of volatile emissions of all (Solanum tuberosom) plants that weigh 60 g.
b. Find a 95% confidence interval for the mean quantity of volatile emissions of all plants that weigh 60 g.
c. Find the predicted quantity of volatile emissions for a plant that weighs 60 g.
d. Determine a 95% prediction interval for the quantity of volatile emissions for a plant that weighs 60 g.
Presuming that the assumptions for regression inferences are met, determine the required confidence and prediction intervals.
