Suppose that extensive testing has revealed that people in Group A have IQ’s that are well described by a N(100, 10) distribution while the IQ’s of people in Group B have a N(105, 10) distribution. What is the probability that a randomly chosen individual from Group A has a higher IQ than a randomly chosen individual from Group B? (a) Write a formula to answer the question. You don’t need to evaluate the formula. (b) Write some R code to answer the question.
