41, 32, 35, 21, 11, 47, 42, 00, 05, 18, 25, 24, 29, 38, 30, 04, 14, 24, 34, 44, 48, 33, 36, 38, 41, 46, 08, 34, 39, 11, 13, 27, 26, 43, 03.
Taking class intervals 0 - 10, 10 - 20, 20 - 30 …., construct frequency as well as cumulative frequency distribution table. Find the number of students obtaining below 20 marks.
Construct the frequency distribution table from the following data :
Ages (in years) No. of children below 4 7 below 7 38 below 10 175 below 13 248 below 16 300 State the number of children in the age group 10 - 13.
Rewrite the following cumulative frequency distribution into frequency distribution:
Less than or equal to 10 = 2
Less than or equal to 20 = 7
Less than or equal to 30 = 18
Less than or equal to 40 = 32
Less than or equal to 50 = 43
Less than or equal to 60 = 50
