In an automated chemical coating process the speed with whic

In an automated chemical coating process, the speed with which objects on a conveyor belt are passed through a chemical spray (belt speed), the amount of chemical sprayed (spray volume), and the brand of chemical used (brand) are factors that may affect the uniformity of the coating applied. A replicated 2³ experiment was conducted in an effort to increase the coating uniformity. In the following table, higher values of the response variable are associated with higher surface uniformity:

Create an ANOVA table for this experiment using alpha = 0.05

Which null hypotheses should be rejected?

Run	Spray Volume	Belt Speed	Brand	Replication 1	Replication 2
	Surface Uniformity
1	-	-	-	39	38
2	+	-	-	25	29
3	-	+	-	30	31
4	+	+	-	50	48
5	-	-	+	45	41
6	+	-	+	25	30
7	-	+	+	30	29
8	+	+	+	51	48

Since, for all effects, F > F₀

So, all effects are significant

Run	Spray	Belt	Brand	Replication	Replication
Volume	Speed	1	2	Total
1	-	-	-	39	38	(1) = 77

5	-	-	+	45	41	c = 54
6	+	-	+	25	30	ac = 55
