(b) What are the populations which are sampled? (c) Is this one or two tailed? (d) Clearly state both the null and alternative hypotheses. (e) Determine terit and tsamp, and/or a p value. (f) What decision do you make about your hypotheses? Briefly, interpret this answer in terms of the actual situation - what is the company's reaction? (g) Construct an appropriate confidence interval for the difference in means the lifetime of the two models. (h) Include an effect size index and interpretation, as appropriate. A).
