Problema Solution

Use the standard normal curve table to find the closest z score for the given condition.

30.2% of the total area is to the right of z.

My answer = 0.52

Answer provided by our tutors

We have:

P(Z > a) = 0.302.

or,

0.5- P(0=< Z =< a) = 0.302

P(0 =< Z =< a) = 0.195

Use the standard normal curve table (find 0.195) => a = .52
