A bank's loan officer rates applicants for credit. The ratings are normally distributed with a mean of 220 and a standard deviation of 6. Find the value of the score at the 30th percentile (P30). Round your answer 2 places after the decimal point.
Given that,
mean = = 220
standard deviation = = 6
Using standard normal table,
P(Z < z) = 30%
=(Z < z) = 0.30
= P(Z < z ) = 0.30
z =-0.52
Using z-score formula
x = z +
x = -0.52 *6+220
x = 216.88
