It is crucial to have a minimum weight difference for each bearing ball before they are assembled into the bearing races. Inspections are constantly being conducted by a factory manager for all production belts to ensure that the bearing balls are in the correct weights. At each round of inspection, five bearing balls are selected randomly from each belt and carefully weighed. A random sample of four inspection belts were selected. The results are as follows: Belt Weight of bearing ball (in grams) 1.22 1.21 1.23 1.20 1 1.22 1.24 1.23 1.22 1.19 1.20 1.19 1.20 1.21 3 1.20 1.20 4 1.19 1.18 1.18 1.18 1.20 a) State an appropriate model and its assumptions. b) By using an ANOVA test, determine whether the weight of bearing balls differs among the production belts? Use a = 0.10.

A manufacturing company glues one part to another part during the assembly of its final product. Either too much or too little glue presents a problem. It is important for the pressure of the glue nozzle (pounds per square inch) to be set correctly because it affects the amount of glue (ounces) that is applied. Ten applications are sampled and the following information collected: SSXX = 129.6 SSYY = 2.345 SSXY = 16.6 X bar = 25.2 Y bar = 2.05 What is the estimated y intercept?
