USING R

12:30 LTE X R assignment - Chapter 11 Wenton Powersports produces dune buggies. They have three assembly lines, Razo "Baze and Tracer,named ater the partioular dune buggy models produced on those ines. Each assembly line was originally designed using the same target production rate However, over the years, various changes have been made to the lines. Accondingly, management wishes to determine whether the assembly lines are soll operating at the same average houy production rae a Cick here for the Excel Data Ele Production data (in dune buggieshour) for the last eight hours are shown in the table above (in "unstacked" format-each group in a separate column) The Excel file contains the same data, but in a "stacked format (the mumeic values for al 3 groups are in a single column). Take a look at the iterence To read the Excel fle into R and view t a. Specify the competing hypotheses to test whether there are some differences in the mean production rates across the three assembly ines Ho Ho b-1. Using the two R commands shown below, run a one way ANONA to test the above hypotheses use the column names un Excel Sie fr te nmenc variable and "Tactor calegorical variable.

Answer 1

a)

Ho:$\mu$_Razor =$\mu$_Blazer =$\mu$_Tracer ; ..

b-1)

Source of Variation	SS	df	MS	F	Pr>F

residual	33.63	21	1.601

b-2)

reject Ho ; we have sufficient evidence........
