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 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 are class boundaries determined in a histogram?By dividing the range by the number of classesBy using the square root of the number of data pointsBy adding 0.5 units to class limitsBy subtracting 0.5 units from class limits

Below is the table showing the number of working hours (per week) of 400 students:Number of Hours Frequency  0 -   9  2010 - 19  8020 - 2920030 - 39100What is the class width for this distribution?Group of answer choices10939varies from class to class

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

What is the correct sequence of steps in making a frequency distribution table for grouped data?*1 pointDetermine the range, divide the range by the desired number of classes, create class intervals, count the frequencies, make the class boundaries and class marksOrganize the data into intervals or classes, count the frequencies, make the class boundaries and class marks, and then determine the range.Determine the range, make the class boundaries and class marks, create class intervals, count the frequencies, and then organize the data into intervals.Organize the data into intervals or classes, determine the range, count the frequencies, and then make the class boundaries and class marks.
