Find a value of z so that z<.02 and 10% of the area under the standard normal curve lies between z and .02

Begin with sketching the problem.

Sketch an approximate z-distribution.

Locate 0.02 on the x-axis.

Then locate a 'z' to the left of it .

Now what is the area of normal curve under z-distribution? [=1]

What is the area of normal curve from z=0 to z=0.2? (use table)

Now continue.....
