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. 101250 "9.7500 .86250 +24107 .16429 *1.4107 1.95000 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.) Wihin Groups Specify the competing hypotheses to test whether there are some differences in the mean production rates across the three assembly lines. e-.. At the 5% significance level, what is the conclusion of the test? What about the 10% significance level? Cck to selctHo. we conclude that the mean buggies/hour differs for some production lines.Explanation / Answer

solutiona:
Solutionb:
optionA:
Solutionc:
p=0.0922
alpha=0.05
p>0.05
Fail to reject null hypothesis
Accept Null hypotehsis
Accept H0.we cannot conclude that mean buggies/hour differs for some production lines
Solutionc2:
alpha=0.10
p=0.0922
p<alpha
Reject nUll hypothesis..
Reject Ho,we can conclude that the mean buggies/hour differs for some production lines
