(Round all intermediate calculations to at least 4 decimal places.) Wenton Power

Question

(Round all intermediate calculations to at least 4 decimal places.)

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. Each 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.

Construct an ANOVA table. Assume production rates are normally distributed. (Round SS, MS, and Fto 2 decimal places and p-value to 4 decimal places.)
