Please solve and answer what z=

Question

Find z such that 5.5% of the standard normal curve lies to the left of z. (Round your answer to two decimal places.)

Answer 1

Hi Tamera,

First, 5.5% is equivalent to 0.055. Recall that on the z-table, values in the interior represent areas to the left of z, so go into the z-table and search for the closest value to 0.055. On my table, that is 0.0548, which corresponds to z= -1.60.

I hope this helps.
