13. FILE Buggies. 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. 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. b. At the 5% significance level, what is the conclusion to the test? what about the 10% significance level? Assume production rates are normally distributed. 2. Refer to the previous question and Patronage data on Connect or Webcampus. Use Fisher's LSD method to determine which means differ at the 5% level of significance (10 points) a) b) Use the Tukey's HSD method to determine which means differ at the 5% level of significance (10 points)
