Find the probability that the sample mean will be more than 133 pounds or less than 121 pounds. Use the TI-83/84 calculator, which shows that the probability that the mean will be between 121 and 133 is 0.98360. How the heck do I do this?

Well, the probability that the mean will be between 121 and 133 pounds is 0.9836, so the probability that the mean will be more than 133 pounds or less than 121 pounds is 1 - 0.9836 = 0.0164

 

Answer: 0.0164
