The marks obtained by a set of students in an exam are recorded in a grouped frequency table.The maximum number of students are found to be in the range of (70-80) marks.If the number of students in the ranges before and after the (70-80) range are equal, which ofthe following is the mode of the data?A) 70 marksB) 75 marksC) 80 marksD) (mode cannot be found as frequency is not given

Find the mode of the following frequency distribution :Marks 10-20 20-30 30-40 40-50 50-60Number of students 12 35 45 25 13

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.

For the following set of scores: 8, 5, 9, 6, 8, 7, 4, 10, 6, 7 9, 7, 9, 9, 5, 8, 8, 6, 7, 10 a. Construct a frequency distribution table to organize the scores. b. Draw a frequency distribution histogram for these data.

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?
