The company developed two new products-one based on chicken livers and the other based on salmon. The conducted an experiment to compare the two new products with its two existing ones, as well as a generic beef-bases product sold at a supermarket chain.
For the experiment, a sample of 50 cats from the population at a local animal shelter was selected. Ten Cats were randomly assigned to each of the five products being tested. Each of the cats was then presented with 3 ounces of the selected food in a dish at feeding time. The researchers defined the variable to be measured as the number of ounces of food that the cat consumed with a 10-minutes time interval that began when the filled dish was presented. The results for this experiment are summarized in the table in the next column and stored in CatFood.
a. At the 0.05 level of significance, is there evidence is there evidence of significant difference in the
b. Compare the result of (a) with those of problem 11.13 (a) on page 413.

Can you explain what this analysis means in layman's terms?
- We calculated that a target sample size of 3626, which was based on anticipated baseline 90-day mortality of 22% and a noninferiority margin of no more than 4 percentage points, would give the trial 80% power, at a one-sided alpha level of 2.5%, accounting for a maximum of 5% loss to follow-up and for early stopping rules for three interim analyses.-
Can you help me understand this analysis?
A 95.7% confidence interval is shown for the intention-to-treat analysis (accounting for alpha spending in interim analyses), and 95% confidence intervals are shown for the other two analyses. The widths of the confidence intervals have not been adjusted for multiplicity. The dashed line indicates the noninferiority margin of 4 percentage points.
