Answer 1

relative frequency, we o frequency which can be by gall calculate first the relative (a) To find cumulative relative need to obtained by the total duiding number of dała ralues (ie total the frequencies & then the cumulatie relative be calculated by adding all the previous relative frequencies Speed frequency relative 'Cunnulatie Frequency felative frequency punasporto priemolirt wird ss-underst 니, st- under 59 3²0 =0,15 0.2+0Ls frequency can all of 4/20 = 0.2 tuketa 0.2 20:35 59 - under 61 6 6/20 =0.3.0.35 +0:3 = 0.65 61- under 63 2 63 - under 65 2/20 = 0.1 0.65 to'l Cool-0.75 5/20 = 0.25 0.75 +0.25 s

Cumulative frequency is calculated by adding frequency from frequency table to y its predecessors each sum the frequency cumulative frequency 4 4+3 = 7 3 7+6 = 13 6 13+ 2 - IS 2 5 Ists = 20 Table Cunulative Less than Cumulative frequency Relative frequency ss 0.2 4 S7 0.35 59 7 0.65 61 13 15 0.75 63 65 1 20
