Question
Need help filling out table:
wenton Powersports produces dune buggies. They have three assembly lines, “Razor," "Blazer," and "Tracer," named after the particular dune buggy models produced on those lines. Ech assembly line was originally designed using the same target production rate. However, over the years, various changes have been made to the lines. Accordingly, management wishes to determine whether the assembly lines are still operating at the same average hourly production rate. Production data (in dune buggies/hour) for the last eight hours are as follows. Razor Blazer Tracer 10 10 10 10 10 13 a. Specify the competing hypotheses to test whether there are some differences in the mean production rates across the three assembly lines. Ho: Razor 1azer- racer. HA: Not all population means are equal. Ho : Razor 1azer Tracer. HA: Not all population means are equal. Ho: Razor 1azer Tracer. HA: Not all population means are equal. b-1. Construct an ANOVA table. Assume production rates are normally distributed. (Round "Sum Sq" to 2 decimal places, "Mean Sq and "Fvalue" to 3, and "p-value" to 4 decimal places.)
