Draw a pie-diagram representing the relative frequencies (expressed as percentage) of the eight classes as given below: 12.6, 18.2, 17.5, 20.3, 2.8, 4.2, 9.8, 14.7

. Find the median of the given data: 8, 9, 12, 7, 5, 4, 18, 20, 6,3

The weight of 8 children are 13.4, 10.6, 12.7, 17.2, 14.3, 15, 16.5, 9.8 find the median weight.

What is the median of the numbers 4.6, 0, 9.3, -4.8, 7.6,2.3,12.7,3.5,8.2,6.1,3.9,5.2?

In the school, 46 students of 9 th standard were told to measure the lengths of the pencils in their compass boxes in centimetres. The data collected was as follows:collected was as follows.16, 15, 7, 4.5, 8.5, 5.5, 5 ,6.5, 6, 10, 12, 13, 4.5, 4.916, 11, 9.2 7.3, 11.4, 12.7 13.916, 5.5, 9.9, 8.4, 11.4, 13.1, 15,4.8, 10, 7.5, 8.5, 6.5, 7.2, 4.5, 5.7, 16, 5.7 6.9, 8.9, 9.2, 10.2, 12.3, 13.7, 14.5, 10 By taking inclusive classes 0-5, 5-10, 10-15... prepare a grouped frequency distribution table

Select the proper fractions from the fractions given below: 5/(9), 11/(8), 23/(25), 19/(20), 18/(17), 3/(8), 12/(7), 5/(11), 15/(13), 17/(27)
