Assume that adults have IQ scores that are normally distributed with a mean of 104.5 and a standard deviation of 19.1. Find the first quartile \( Q_1 \), which is the IQ score separating the bottom 25% from the top 75%. (Hint: Draw a graph.)The first quartile is [ ].(Type an integer or decimal rounded to one decimal place as needed.)
