Question

Two Way ANOVA

A mechanical engineer is studying the thrust force developed by a drill press. He suspects that the drilling speed and the feed rate of the material are the most important factors. He selects four feed rates and uses a high and low drill speed chosen to represent the extreme operating conditions. He obtains the following results.

(A)		Feed	Rate (B)
Drill Speed	0.015	0.030	0.045	0.060
125	2.70	2.45	2.60	2.75
	2.78	2.49	2.72	2.86
200	2.83	2.85	2.86	2.94
	2.86	2.80	2.87	2.88

Analyze the data (TWO WAY ANOVA) and draw conclusions. Use a = 0.05.

DO HYPOTHESIS TESTING and show steps how to insert data into EXCEL.
