# Question: Employees in a large manufacturing plant worked an average of

Employees in a large manufacturing plant worked an average of 62.0 hours of overtime last year, with a standard deviation of 15.0 hours. For a simple random sample of n = 36 employees and x = the number of overtime hours worked last year, determine the z-score corresponding to each of the following sample means:

a. x-bar = 55.0 hours

b. x-bar = 60.0 hours

c. x-bar = 65.0 hours

d. x-bar = 47.0 hours

a. x-bar = 55.0 hours

b. x-bar = 60.0 hours

c. x-bar = 65.0 hours
