Do you know how to use a standard normal distribution table to find the cumulative probability for a z value of 0.86? You can find a suitable table here: http://lilt.ilstu.edu/dasacke/eco148/ztable.htm

I can read the table but isn't there more to it than just finding the number on the graph?

kropot72 · Answer

If you find the cumulative probability for a z value of 0.86, you will have the decimal fraction of the area under the normal curve that lies to the left of the z value 0.86. If we call this fractional area 'a' then the required area is given by
$$1.0000-a=?$$
Note that the total area under the normal curve is 1.

so my equation would read 1.0000-0.8051?
