A radio station claims that the amount of advertising per hour of broadcast time has an average of 12 minutes and a standard deviation equal to 2.4 minutes. You listen to the radio station for 1 hour, at a randomly selected time, and carefully observe that the amount of advertising time is equal to 5 minutes. Calculate the z-score for this amount of advertising time. O z= 0.22 O z= -2.92 O z= -0.22 O z= 2.92
