Answer 1

Answer:

mean= 75.6  mode = 85

Step-by-step explanation:  (sum of all values )/number of observation

= 1890/25=75.6

mode is easy as 85 mostly occured so 85 is mode

Answer 2

Mean = 75.6 ,  Median = 77  & Mode = 85

Step-by-step explanation:

total of 25 patients

blood sugar results obtained

87,61,83,67,85,77,69,76,65,85,85,54,79,68,80,73,78,68,85,73,81,78,81,77,75

arranging in ascending order

54 , 61  , 65 , 67 , 68, 68, 69 , 73 , 73, 75, 76 , 77, 77, 78, 78 ,  79 , 80, 81, 81, 83 ,85 , 85, 85 , 85 , 87

Median will be 13th term

77 is Median

85 is repeated maximum 4 time

Mode = 85

Mean =( 54 + 61 + 65 + 67 + 68 + 68 + 69 + 73 + 73 +75 + 76 + 77 + 77 + 78 + 78 +  79 + 80 + 81 + 81 + 83 + 85 + 85 + 85 + 85 + 87 )/25
