Please do not give solution in image format thanku The population distribution of scores on a commonly used IQ test is normal with a mean of 100 and a standard deviation of 15. The test was recently administered to a sample of psychology undergraduates and to a sample of mildly depressed psychiatric patients. Both groups yielded normally distributed IQ scores. The standard deviation of the students' scores was 12 and that of the patients' was 17. The probability that a psychology student has a lower IQ than the average person in the population was found to be 10 percent. The probability that a patient has a higher IQ than the average psychology student is 5 percent. a) What is the probability that a randomly selected psychology student will have a lower IQ than the average psychiatric patient? b) What percentage of people from the general population will have a higher IQ than a student at the 67th percentile of the psychology student distribution?
