Inoue et al. (A-41) studied donor cell type and genotype on the efficiency of mouse somatic cell cloning. They performed a factorial experiment with two donor cell types (Sertoli cells or cumulus)

and six genotypes. Outcome variables were the cleavage rate and the birth rate of pups in each treatment combination.

For the studies described in Exercises 39 through 66, do the following:

(a) Perform a statistical analysis of the data (including hypothesis testing and confidence interval construction) that you think would yield useful information for the researchers.

(b) Determine p values for each computed test statistic.

(c) State all assumptions that are necessary to validate your analysis.

(d) Describe the population(s) about which you think inferences based on your analysis would be applicable.
