Answer 1

solution : From data are given get minimum observation of & maximum observation 48. The unit place are to be treated as leaves and tenth place number treated as stem. clearly in given data stems are 0,112, 3, 4 Accordingly we - prepose stem & leaf chart as follows; stem - Leaf 9,7 7,6,8,5, 1; 9,8,8,8,9,4,7, 2,5 3,5, 2, 2, 9, 3, 6, 4, 8, 6, 7, 9; 6,4 6,4,29,0,3,2,1, 9.,0,7,7,1 4,2, 6, 6, 2,0,8 2 3 4 In the above table first of all we have entered the leares according to order of orcemence. However we arrange them in the ascending order as follows: stem Leaf 7,8 1, 2, 4, 5, 5, 6, 77,8,8,8,8, 9, 9 1, 2, 2, 3, 3, 4, 4, 5, 6, 6, 6, 8, 9, 9, 0,0,1,1, 2, 2, 3, 4, 6, 7, 7, 9, 9 012, 2, 4, 6, 6,8 o - 2 3 o 4

Leaf - 1 # split stem & leaf chart as as follows: stem 79 1, 2, 4 5, 5, 6, 7, 7, 8, 8, 8, 8, 9 9 1,2,2, 3, 3, 4,4. 5, 6, 6, 6, 8, 9, 9 0,0,1,1) 2, 2, 3, 4 6, 7,7 9,9 4. 0, 2, 2, 4 d 4 6,618 2 2 3 3 Where first part should contain the leaves o to 4 f second part should contain the leaves 5 to 9
