IQ scores in a large population have a normal distribution with mean=100 and standard deviation=15. What is the probability the sample mean for n=2 will be 121 or higher? (I understand the z score equals 1.98,could you please explain to me how the final answer is equal to 0.0239?thanks.) Also, why do we use 1 and subtract 0.9761 to get 0.0239? Where does 0.9761 come from?

Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 20. Use the empirical rule to determine the following: (a) What percentage of people has an IQ score between 60 and 140? (b) What percentage of people has an IQ score less than 60 or greater than 140? (c) What percentage of people has an IQ score greater than 160?
