The data below is a frequency distribution of the Intelligence Quotient (IQ) of 200 students taking up Behavioral Psychology and Business Statistics in a certain university: C.I. 131 – 135 7 126 - 130 10 121 - 125 14 116 - 120 35 111 - 115 42 106 - 110 21 101 - 105 18 96 - 100 29 91 - 95 10 86 - 90 14 n= 200 A. Find the following: 1. Class interval size 2. Class midpoint of the 4th class of the highest frequency 3. Lower class boundary of the highest class interval 4. Upper class limit of the 5th class interval (begin from the bottom) 5. Number of students whose IQ is greater than 115.5 6. Number of students whose IQ is less than 96.5 7. Number of students whose IQ is between 126 – 130 8. Lowest upper class limit 9. Highest upper class limit 10. Upper class boundary of the 3d class interval
