Alarge manufacturing firm tests job applicants who recently graduated from college. the test scores are normally distributed with a mean of 500 and a standard deviation of 50. management is considering placing a new hire in an upper level management position if the person scores in the upper 6 percent of the distribution. what is the lowest score a college graduate must earn to qualify for a responsible position?

The lowest score a college graduate must be 577.75 or greater to qualify for a responsible position and lie in the upper 6%.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 50

We are given that the distribution of test score is a bell shaped distribution that is a normal distribution.

Formula:

We have to find the value of x such that the probability is 0.06.

P(X > x)  = 6% = 0.06

Calculation the value from standard normal z table, we have,  

Hence, the lowest score a college graduate must be 577.75 or greater to qualify for a responsible position and lie in the upper 6%.
