The effect of two factors---per-chamber volume ratio (V) and injection timing (T) on the parts per million of noxious gas emitted from an engine was studied. The volume ratio was set at three equi-spaced levels and the time was set at three equi-spaced levels. Two engines were built for each of the nine treatment combinations and the amount of the gas emitted was recorded for the 18 engines as shown in the Table.

- A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 48 of 100 individuals prefer Brand A. Complete parts a through c.
