Question

Find the median, range, and interquartile range of both sets: Set 1: 65, 66, 77, 79, 81, 93, 104, 105 Set 2: 56, 1, 29, 72, 67, 59, 74, 60

Answer 1

Answer:

Have a nice day

Step-by-step explanation:

set 1 ,

 median = 4th observation + 5th observation/ 8

                = 79 + 81 /2

                = 160/2

median    = 80

range =   highest observation -lowest observation

range =   105 - 65

          = 40

set 2,

Arrange the set in ascending order

1,29,56,59,60,67,72,74

median = 4th observation + 5th observation/ 8

             =59 + 60 / 8

             =14.875

range =  highest observation -lowest observation

range =   74 - 1

           = 73
