Use the theory of Exercises 14.24 and 14.26, as well as the quantities already calculated in Exercise 14.51 for the data of Exercise 14.42, to find

(a) A 99% confidence interval for the expected number of deaths in a group of 25 mice when the dosage is 9 milligrams;

(b) 99% limits of prediction of the number of deaths in a group of 25 mice when the dosage is 9 milligrams.

(b) 99% limits of prediction of the number of deaths in a group of 25 mice when the dosage is 9 milligrams.

## Answer to relevant Questions

Redo Exercise 14.61 when the dosage is 20 milligrams. Note the greatly increased width of the confidence limits for the expected number of deaths and of the limits of prediction. This example illustrates that extrapolation, ...The following data pertain to x, the amount of fertilizer (in pounds) that a farmer applies to his soil, and y, his yield of wheat (in bushels per acre): Assuming that the data can be looked upon as a random sample from a ...If the row categories as well as the column categories of an r × c table are ordered, we can replace the row headings and also the column headings by consecutive integers and then calculate r with the formula obtained in ...The regression models that we introduced in Sections 14.2 and 14.6 are linear in the x’s, but, more important, they are also linear in the β’s. Indeed, they can be used in some problems where the relationship between ...Prove Theorem 15.6.
