A start-up company is about to market a new computer
printer. It decides to gamble by running commercials during a
championship game. The company hopes that name recognition will be
worth the high cost of the ads. The goal of the company is that
over 35% of the public recognize its brand name and associate it
with computer equipment. The day after the game, a pollster
contacts 415 randomly chosen adults and finds that 179 of them know
that this company manufactures printers. Would you recommend that
the company continue to advertise during the
championship game? Explain. (Consider a result to be
surprising if the probability of observing it given your
expectations is less than 0.05.)
