Wenton Powersports produces dune buggies. They have threeassembly lines, “Razor,” “Blazer,” and “Tracer,” named after theparticular dune buggy models produced on those lines. Each assemblyline was originally designed using the same target production rate.However, over the years, various changes have been made to thelines. Accordingly, management wishes to determine whether theassembly lines are still operating at the same average hourlyproduction rate. Production data (in dune buggies/hour) for thelast eight hours are as follows.

Razor				Blazer				Tracer
	11				10				9
	10				8				9
	8				11				10
	10				9				9
	9				9				8
	9				10				7
	13				13				8
	11				8				9

a. Specify the competing hypotheses to testwhether there are some differences in the mean production ratesacross the three assembly lines.

• H₀: ?_Razor =?_Blazer = ?_Tracer.H_A: Not all population means are equal.

• H₀: ?_Razor ??_Blazer ? ?_Tracer.H_A: Not all population means are equal.

• H₀: ?_Razor ??_Blazer ? ?_Tracer.H_A: Not all population means are equal.

b-1. Construct an ANOVA table. Assumeproduction rates are normally distributed. (Round "SumSq" to 2 decimal places, "Mean Sq" and "Fvalue" to 3, and "p-value" to 4 decimalplaces.)

b-2. At the 5% significance level, what is theconclusion to the test?

b-3. What about the 10% significance level?
