Question
Homewarkt 8-Chapter 13 × Round all intermediate calculations to at least 4 decimal places.) Wenton Powersports produces dune buggies. They hae 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 huwe been made to the lines. Accordingy, management wishes to determine whether the assembly lines are stil operating at the same average hourty production rate. Production data (in dune buggies/hour) for the last eight hours are as follows 10 10 10 10 13 r . 101250 sf = 2.4107 x2 = 97500 1.6429 x-82500 s-07857 a. Construct an ANOVA table. Assume production rates are normally distributed (Round SS, MS, and F to 2 decimal places and p-value to 4 decimal places.) ANOVA of v MS Between Groups Within Groups Total b. Specify the competing hypotheses to test whether there are some differences in the mean production rates across the three assembly lines
Explanation / Answer
AT 0.05 LOS
null, Ho: Urazor = Ublazer = U tracer
alternative, HA:not all population means are equal
degrees of freedom between = k - 1 = 3 - 1 = 2
degrees of freedom Within = n - k = 24 - 3 = 21
degrees of freedom Total F( k-1,n - k,) at 0.05 is = F Crit = 3.467
F Cal = 4.88
We got |F cal| = 4.88
& |F Crit| =3.467
MAKE DECISION
Hence Value of |F cal| > |F Crit|and Here We reject Ho
AT .01 LOS
degrees of freedom between = k - 1 = 3 - 1 = 2
degrees of freedom Within = n - k = 24 - 3 = 21
egrees of freedom Total F( k-1,n - k,) at 0.01 is = F Crit = 5.78
make decision
value of |F cal| < |F Crit|and here we don't reject Ho
