P( Z<z) =0.1492 what is the answer ?

P( Z<z) =0.1492

what is the answer ?

Expert Solution

Standard normal distribution:

Using an online calculator the z scores are determined.

Z-scores are expressed in terms of standard deviations from their means value. The z-scores have a distribution with a mean of 0 and a standard deviation of 1.

According to the table, 0.15 (actually 0.1492) is the probability of being below -1.04. By symmetry, 0.15 must also be the probability of being above +1.04. Using the calculator, we can enter 0.15 exactly and find that the corresponding z-score is actually -1.036 giving a final answer of z = +1.036 or +1.04 if we round to two decimal places which is our preference
