The amount of advertising per hour of broadcast time has an average of 17 minutes and a standard deviation equal to 2.7 minutes. At a randomly selected time, you observe the broadcast for 1 hour and carefully observe that the amount of advertising time is equal to 9 minutes. Calculate the z- score for this amount of advertising time. Oz = -0.37 z = -2.96 z = 0.37 Oz = 2.96
