If 35 is removed from the data: 30,34,35,36,37,38,39,40, then the median increases by 2         (b)  1.5            (c)  1        (d)  0.5

Explanation

The given data is `30,34,35,36,37,38,39,40`

Here n=8

median=((n/2)^(th) term +(n/2+1)^(th) term)/2`

=((4)^(th) term+(5)^(th) term)/2`

=`(36+37)/2=36.5`

if 35 is removed then new data is `30,34,36,37,38,39,40`

n=7

median=`((7+1)/2)^(th) term `
