A radio station claims that the amount of advertising per hour of broadcast time has an average of 16 minutes and a standard deviation equal to 2.7 minutes. You listen to the radio station for 1hour, at a randomly selectedtime, and carefully observe that the amount of advertising time is equal to 10 minutes. Calculate thez-score for this amount of advertising time. Can someone explain to me what I need to be using to find this z-score? i'm not sure which numbers I need to use, and which are there to throw me off.
