Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion (.02) and its Z score. Insert the value in the above equation and solve for the score. Remember that the Z score will be negative.

**Ashok Khile**, Saturday, January 21, 2012 at 2:36amHere mean = 35

s.d.= 4

we have asked that

P(z)=0.98

see normal table

It is z=2.05

remember it is standard normal table value but we have to convert it for x variable for which mean is 35 and s.d. is 4.

do the inverse operation for which we convert x into z.

i.e.

x=mean+z*s.d.

x=35+2.05*4

x=47.3

rounding off it will be 48.

That is answer is 48.
