One-way ANOVA Assume you are employed by a consumer products rating service and your assignment is to assess car batteries.  For this part of your investigation, you want to determine if there is a difference in useful life among the top-of-the-line car batteries produced by three manufacturers (A, B, and C).  To provide the data base for your assessment, you randomly sample four batteries from each manufacturer and run them through laboratory tests which allow you to determine the useful life of each battery.  The following are the results given in months of useful battery life:                                                             Battery Manufacturer                     A                    B                       C                    52                   46                      44                    57                   52                      33                    55                   51                       50                    59                   50                       51 State H0 and Ha With ∝ = .05, find fcrit Compute fobt What is the conclusion?

Two-Way ANOVA… A random sample of welfare recipients was assigned to a new job training program. Another random sample was assigned to a conventional job training program. (NOTE:  Which of the job training programs they were assigned to is one of the ways in which the subjects were classified). Subjects were also classified according to whether or not they had a high school diploma. All of the subjects in each group found employment in the private sector at the end of their training. Their mean hourly wages are shown in this table:                                                       NEW            CONVEN.        HS DIPLOMA            M= $8.88      M=$8.75                         M=  $8.82        NO HS DIPL0MA    M= $4.56      M=$8.80                         M= $8.80                                                      M=$6.72     M=$8.78    1. Name the two factors (you decide which one is Factor A and which one is Factor B). 2. How would you calculate Fobt for Factor A (use the above numbers in your explanation…no computations needed)? 3. How would you calculate Fobt for Factor B? 4. How would you calculate Fobt for the Interaction in this study?
