Answer 1

Solution :-→ we have to construct a steam - leat diagram of the percentages with one line per steam. >> 20 steam- leaf plot it seeppose 42 we take then 4 is steam and 2 is leat. Steam Wuite onces and leaf write infornt of Steam times comes in given observations. io Steam - leaf diaggiam is below. 1 1 1 1 2 3 6666 8 99 2 1 0 1 2 5 5 66 777 888 9 310 1 1 1 1 22 66 777 99 as many 410 1 1 1 1 3 5 5 7 8 9 we => Now, by 200 (2) Now have to find eight classes for cut point grouping such that smallest Value 133.3 and largest Value 325.5 lies in this classes ule: => classes width is multiple of 5. We take smaller end point of first class is 130 and largest end point of last class is 330 Then difference = 330 -130 = 200 NOW we divide 200 total classes 8. i width of a class = 25. oo 25 is multiple of 5 cö classes fou cutpoint grouping is below. 130 - under -155 155 - Under-180 180 205 - Under 230 - under - 255 255 - under – 280 280 - under - 305 305 - under - 205 230, unden – 330

have any -> hope you understand. Dt you doubt then comment it. Thank you
