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. (You may find it useful to reference the F table.) Razor Blazer Tracer 11 10 9 10 8 9 8 11 10 10 9 9 9 11 8 9 10 7 12 11 8 12 8 9

a. Specify the competing hypotheses to test whether there are some differences in the
multiple choice
-
H0: μRazor = μBlazer = μTracer. HA: Not all population means are equal.
-
H0: μRazor ≤ μBlazer ≤ μTracer. HA: Not all population means are equal.
-
H0: μRazor ≥ μBlazer ≥ μTracer. HA: Not all population means are equal.
