Question: A study showed that 56 of 80 people who saw a TV advertisement for potato chips during a comedy and 38 of 80 people who saw the same TV ad during a football game remembered the brand name two hours later. Assuming that the samples were randomly selected and that the cost of running the ad during the two programs is equal, determine if we can conclude at an alpha of .01 if it is more cost effective to advertise during one TV program than the other.
