The probability that a randomly chosen employee is a line worker who plans to retire at age 65 is found by dividing the frequency of line workers who plan to retire at age 65 by the total number of employees. This gives us:

P(line worker who plans to retire at age 65) = 57/181

Calculating this gives us a probability of approximately 0.315, which is answer choice D.
