Metalworks, a supplier of fabricated industrial parts, wants to determine if the average output rate for a particular component is the same across the three work shifts. However, since any of four machines can be used, the machine effect must be controlled for within the sample. The accompanying table shows output rates (in units) for the previous day. (You will need to calculate the t-statistic, for the given α and df per the ANOVA Error row.)
Machine (Factor B) Shift (Factor A)
1 2 3
A 1392 1264 1334
B 1228 1237 1107
C 1173 1108 1186
D 1331 1342 1387

Click here for the Excel Data File (Beware! that the upper-left two cells in this file are merged; you will need to unmerge them for the Excel ANOVA tool to work properly; or smply retype the dataset, as it is so small.)

a-1. Construct an ANOVA table. (Round intermediate calculations to at least 4 decimal places. Round "SS", "MS" to 4 decimal places and "F", "p-value" to 3 decimal places.)
