Example The nearby table shows measurement results for a metal product
produced by a heat treatment process based on two treatment levels:
time (A) and temperature (B). The experiments were repeated twice
each under identical conditions.
Perform analysis of variance on the following null hypothesis, using a signifi-
cance level of 5%.
H
0
: No change in strength due to time
H
0
: No change in strength due to heat treatment temperature
H
0
: No change in strength due to interaction of time and heat treatment
