The width of each of five continuous classes in a frequency distribution is 5 and the lower class limit of the lowest class is 10. The upper class limit of the highest class isa.15b.40c.25d.35

How is the class width determined in a continuous frequency distribution?By subtracting the highest value from the lowest valueBy dividing the range by the number of desired classesBy multiplying the range by the number of desired classesBy taking the square root of the range

The frequency distribution table of heights (in centimeters) of a group of students with a class width of 6 are as follows: 150, 152, 154, 156, 158, 160, 162, 164, 166, 168. What is the lower boundary of the class interval 156-161?Group of answer choices161.5160155.5156.5

For a grouped frequency distribution having eight classes, the upper class boundaries of the lowest and the highest classes are 10 and 66 respectively. What is the lower class boundary of the highest class?

The four classes: less than 5, 5 to < 10, 10 to < 20, greater than 20, would be acceptable for developing a frequency distribution.

From the given frequency table, find the class mark of the class interval having the highest frequency.
