An experiment that was carried out to study how flow rate through a solenoid valve in an automobile's pollution-control system depended on three factors: armature lengths, spring load, and bobbin depth. Four different levels (low, moderate, high, and extreme) of each factor were chosen, and a single observation on flow was made for each combination of levels. The resulting data set consisted of how many observations? Show how you derived your answer.
