Question 2
The Best Pet Food company has a business objective of expanding its product line beyond its current Kidney and Salmon cat food. The company developed two new products, one based on Chicken Liver and the other based on Beef. The company conducted an experiment to compare the two new products with its two existing ones, as well as a generic Shrimp-based product sold in a supermarket chain. For the experiment, a sample of 55 cats was selected at the Toronto Humane Society. A random selection of eleven cats were assigned to each of the five products being tested. Each of the cats was then presented with 4.5 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 within a 5-minute interval that began when the filled dish was presented. The results of this experiment are given below.

H0: Select an answer a H1: Select an answer Which one is the claim? \"HI NHO For part (b), round your answer to 6 decimal places. (b) What is the test P-value that should be used in your hypothesis test? :] (C) Is the null hypothesis rejected? " No Yes (d) Is the claim supported? " Yes, at the 5% level of significance there is enough evidence to conclude that there is a difference in the mean amount of food eaten among the various products. No, at the 5% level of significance there is not enough evidence to conclude that there is a difference in the mean amount of food eaten among the various products
