Test, Confidence Interval, and Distribution Calculations
kExample 2:
The values in the table below are measurement results that show how the durability of a metal product is affected by changes in heat treatment time (A) and temperature (B). Experiments were conducted twice under each condition.
| Temperature B1 | Temperature B2 |
Time A1 | 113, 116 | 139, 132 |
Time A2 | 133, 131 | 126, 122 |
|

Perform analysis of variance on the null hypotheses listed below, using a 5% level of significance.
H0 : Change in time does not affect durability.
H0 : Change in treatment temperature does not affect durability.
H0 : Changes in time and treatment temperature do not affect durability.
