Problem 1 In the last decade stockbrokers have drastically changed the way they do business. Internet trading has became quite common and online trades can cost as little as $7. It is now easier and cheaper to invest in the stock market than ever before. What are the effects of these changes? To help answer this question, a financial analyst randomly sampled 366 American households and asked each to report the age of the head of the household and the proportion of their financial assets that are invested in the stock market. The age categories are: Young (under 35) Early middle age (35 to 40) Late middle age (50 to 65) Senior (over 65) The analyst was particularly interested in determining whether the ownership of stocks varied by age. Do these data allow the analyst to determine that there are differences in stock ownership between the four age group? Check the required conditions. Use 5% as a significance level

Problem 2 A pet food company has a business objective of expanding its product line beyond its current kidneyand shrimp-based cat foods. The company developed two new products, one based on chicken livers and the other based on salmon. The company conducted an experiment to compare the two new products with its two existing ones, as well as a generic beef-based product sold in 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 within a 10=minute time interval that began when the filled dish was presented. The result for this experiment are summarized in the following table.
