3. Researchers wanted to determine if carpeted rooms contained more bacteria than uncarpeted rooms. To determine the amount of bacteria in a room, researchers pumped the air from the room over a Petri dish at the mic of one cubic foot per minute for eight carpeted rooms and eight uncarpeted rooms. Colonies of bacteria were allowed to form in the 16 Petri dishes. The readis are presented in the isble below. The data seem in be normally distributed with no outliers. Do carpeted rooms have more bacteria than uncarpeted rooma at the 0.05 level of significance ?
