Question

For the given distribution, draw the less than and greater than cumulative frequency curves.
`{:("Class Interval",0-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Frequency",5,3,7,2,14,9,15,10):}`

Answer 1

Less than cumulative frequency distribution:
`{:("Upper Class","Frequency","Less than Cumulative"),("Boundary",,"Frequency"),(" "10," "5," "5),(" "20," "3," "8),(" "30," "7," "15),(" "40," "2," "17),(" "50," "14," "31),(" "60," "9," "40),(" "70," "15," "55),(" "80," "10," "65):}`
Greater than cumulative frequency distribution:
`{:("Lower Class","Frequency"," ""Greater than "),("Boundary",,"Cumulative Frequency"),(" "0," "5," "65),(" "10," "3," "60),(" "20," "7," "57),(" "30," "2," "50),(" "40," "14," "48),(" "50," "9," "34),(" "60," "15," "25),(" "70," "10," "10):}`
