If the given data is represented as a group frequency table with classes 160 – 165, 165 – 170 etc., how many such classes are required?

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.

What is the frequency of the class 11-20 in the below given data?

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