Answer 2

Answer:

mean=sum of all observation/number of observation

=68+49+38+41+49+54+89+99+66/9

=554/9

mean=61.55

median

arranging data in ascending order

38,41,49,54,67,68,89,99

number of observation=n=9(odd number)

median=(n+1/2)th observation

=(9+1/2)th observation

=5th observation

median,=54

mode

68,49,-38,41,49,54,89,99,67

mode=49
