You're on a roll — The problem involves analyzing grouped data for the number of cars passing through a checkpoint over 32 days. The "Number of cars" intervals are given as -10, -20, etc. Assuming these are midpoints of class intervals and ignoring the negative signs (as car counts cannot be negative), we interpret the data as follows: | Number of cars (Midpoint, x) | Frequency (Number of days, f) | Class Interval | fx | fx^2 | Cumulative Frequency (CF) | |:-------------------------------:|:--------------------------------:|:--------------:|:----:|:-------:|:-------------------------:| | 10 | 2 | 5-15 | 2
