II.
The significance of the main effect of temperature can be tested.
a.

For numbers 17 to 20: A study was conducted to determine the bubble formation of milk as affected by
various factors: type of milk (M1, M2), temperature (T1, T2), and processing speed (S1, S2, S3). Three
companies participated. Bottled milk from each type was randomly selected. Each bottle content was
then divided into two portions and stored at different temperatures. After three hours, stored milk was
divided into three where each portion was randomly subjected to a speed of shaking to form the
bubbles. The volume of bubbles formed was measured thereafter. The partial analysis of variance table
is shown below:
