An investigator has a colony of rats

For Exercise 6.6 compute the estimated relative efficiencies of

a. regression estimation to ratio estimation.

b. regression estimation to difference estimation.

c. ratio estimation to difference estimation.

Which method of estimation do you recommend?

Exercise 6.6

An investigator has a colony of rats that have been subjected to a standard drug. The average length of time to thread a maze correctly under the influence of the standard drug was found to be seconds. The investigator now would like to subject a random sample of 11 rats to a new drug. Estimate the average time required to thread the maze while under the influence of the new drug. (The data are shown in the accompanying table.) Place a bound on the error of estimation. [Hint: Employing a ratio estimator for my is reasonable if we assume that the rats will react to the new drug in much the same way as they reacted to the standard drug.] What is the most unusual feature of the scatter plot for these data?
