1Q Scores. In Exercises 5-12, assume that adults have IQ scores that are normally dis- tributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler test). (Hint: Draw a graph in each case.) 5. Find the probability that a randomly selected adult has an IQ that is less than 130.
A college admissions officer for an MBA program has determined that historically applicants have undergraduate grade point averages that are normally dis- tributed with a standard deviation of 0.4. From a random sample of 16 applications from the current year, the sample mean grade point average is 2.5. (a) (5 points) Find a 95% confidence interval for the population mean. (b) Based on these sample results, a statistician computes for the popula- tion mean a confidence interval extending from 2.39...
