Assignment 10 — Problems 9.92 STUDY OF MUTUAL FUND PERFORMANCE. Mutual funds are classified as large-cap funds, medium-cap funds, or small-cap funds, depending on the capitalization of the companies in the fund. Hawaii Pacific University researchers investigated whether the average performance of a mutual fund is related to capitalization size (American Business Review, January 2002). Independent random samples of 30 mutual funds were selected from each of the three fund groups, and the 90-day rate of return was determined for each fund. The data for the 90 funds were subjected to an analysis of variance, with the results shown in the ANOVA summary table below. Fund group 2 409.566 204.783 6.965 .002 Error 87 2,557.860 29.401 Total 89 2,967.426 Source: S. W. Shi and M. ]. Seiler, “Growth and Value Style Comparison of U.S. Stock Mutual Funds,” American Business Review, January 2002 (Table 3). Published by American Business Review, © 2002. a. State the null and alternative hypotheses for the ANOVA. b. Give the rejection region for the test using a = .01. c. Make the appropriate conclusion using either the test statistic or the p-value.
9.98 [Data Set: CARTON] A MANAGERIAL DECISION PROBLEM. A direct-mail company assembles and stores paper products (envelopes, letters, brochures, order cards, etc.) for its customers. The company estimates the total number of pieces received in a shipment by estimating the weight per piece and then weighing the entire shipment. The company is unsure whether the sample of pieces used to estimate the mean weight per piece should be drawn from a single carton, or whether it is worth the extra time required to pull a few pieces from several cartons. To aid management in making a decision, eight brochures were pulled from each of five cartons of a typical shipment and weighed. The weights (in pounds) are shown in the table. .01851 .01872 .01869 .01899 .01882 .01829 .01861 .01853 01917 .01895 .01844 .01876 .01876 .01852 .01884 .01859 .01886 .01880 .01904 .01835 .01854 .01896 .01880 .01923 .01889 .01853 .01879 .01882 .01905 .01876 .01844 .01879 .01862 .01924 .01891 .01833 .01879 .01860 .01893 .01879 a. Identify the response, factor(s), treatments, and experimental units. b. Do these data provide sufficient evidence to indicate differences in the mean weight per brochure among the five cartons? c. What assumptions must be satisfied in order for the test of part b to be valid? d. Use Tukey’s method to compare all pairs of means, with a = .05 as the overall level of significance. e. Given the results, make a recommendation to management about whether to sample from one carton or from many cartons.
9.52 [Data Set: L09052] A randomized block design was used to compare the mean responses for three treatments. Four blocks of three homogeneous experimental units were selected, and each treatment was randomly assigned to one experimental unit within each block. The data are shown below, followed by a StatCrunch ANOVA printout for this experiment.

Case information:
Globo Gym Services Pty Ltd is a provider of maintenance services for
commercial gym equipment. Gyms throughout Australia engage Globo
Gym Services to maintain their gym equipment. As a company specialising
in gym equipment maintenance, Globo Gym is able to provide clients with
efficient and timely repairs, more cost efficiently than gyms could
otherwise undertake through employing their own staff.
The COVID-19 pandemic has hit gyms particularly hard, with lock downs
forcing gym closures across different states in Australia. For Globo Gym
Service, this has meant that clients have cut back requesting equipment
maintenance and reduced system maintenance requests as much as
possible. Many clients are experiencing great financial difficulty and have
delayed paying amounts owed to Globo Gym Services.
