Question

Legionnaires’ disease In 1974, the Bellevue-Stratford
Hotel in Philadelphia was the scene of an outbreak of what
later became known as legionnaires’ disease. The cause of
the disease was finally discovered to be bacteria that
thrived in the air-conditioning units of the hotel. Owners

of the Rip Van Winkle Motel, hearing about the Bellevue-
Stratford, replaced their air-conditioning system. The

following data are the bacteria counts in the air of eight
rooms, before and after a new air-conditioning system wasinstalled (measured in colonies per cubic foot of air). Has
the new system succeeded in lowering the bacterial count?
Base your analysis on a confidence interval. Be sure to list
all your assumptions, methods, and conclusions.
