Breitling sells men's gold, silver, and titanium watchbands. A random sample of each type was obtained (in similar styles), and the weight of each watchband (in grams) was recorded. The data are given in the following table.
a. Conduct an analysis of variance test to determine whether there is any evidence that the mean weights of any two watchband types are different. Include an ANOVA table. Use a = 0.01. Write a Solution Trail for this problem.
b. Compute the sample mean weight for each sample. Given your conclusion in part (a), which pair(s) of population means do you think are different?
