Answer all questions ### Scores Attained by High School Graduates in an Entrance Exam for CollegeThe table below presents the scores attained by high school graduates in a college entrance exam. The data is organized into class intervals, with corresponding frequencies and columns designated for various statistical calculations.| Class Interval | Frequency (f) | Midpoint (x) | fx | Deviation (d) | fd ||----------------|---------------|--------------|----|---------------|----|| 65 - 69 | 2 | | | | || 70 - 74 | 8 | | | | || 75 - 79 | 10 | | | | || 80 - 84 | 9 | | | | || 85 - 89 | 7 | | | | || 90 - 94 | 2 | | | | || 95 - 99 | 2 | | | | |Total: n =\[\sum fx = \]\[\sum fd = \]### Explanation of Terms:- **Class Interval**: The range of scores grouped together.- **Frequency (f)**: The number of students who scored within the given class interval.- **Midpoint (x)**: The midpoint of each class interval. It is calculated as the average of the lower and upper bounds of each interval.- **fx**: The product of the frequency and the midpoint of each class interval.- **Deviation (d)**: The difference between each midpoint and a reference value.- **fd**: The product of the frequency and the deviation of each class interval.### Steps to Complete the Table:1. **Determine the Midpoint (x) for Each Class Interval**: - For the interval 65-69, the midpoint is (65+69)/2 = 67. - Repeat this calculation for each interval.2. **Calculate fx**: - Multiply the frequency (f) by the midpoint (x) for each interval.3. **Calculate d**: - Choose a reference value (often the median class midpoint or mean midpoint) and subtract each interval’s midpoint from this reference.4. **Calculate fd**: - Multiply the frequency (
