Giraffes have excellent vision. Refér to (Oct. 2013) study of a giraffe's eyesight, Exercise 7.38 (p. 334). Recall that the researchers measured the eye mass for a sample of 27 giraffes native to Zimbabwe, Africa, and found x 53.4 grams and s = 8.6 grams. Suppose the ob- %3D %3D jective is to sample enough giraffes in order to obtain an estimate of the mean eye mass to within 3 grams of its true value with a 99% confidence interval. loval
