Dr. Jain in computer science has developed an app that collects students' online class deadlines and organizes them into a schedule that includes due dates as well as scheduled reminders to start working on assignments before those deadlines. Dr. Jain wants to test this app, but only wants to include people with "close to normal" IQ. Because of this, she only plans to include participants with IQ scores in the middle 75% of the population. (1 point) Lower Z-score Middle 75% of the IQ Distribution Upper Z-score a. Using the information provided above, what z-score would correspond with the upper IQ cutoff and what z-score would correspond with the lower IQ cutoff for this study? b. Based on the z-scores you found in question 1a, calculate the raw IQ scores that would correspond with those upper and lower cutoffs. The population mean for this standardized IQ is 100 and the standard deviation is 15 (Show your work earn full credit; only 1/2 credit if no work is shown)
