The average hourly wage of workers in a fast food restaurant is $5.85 with a standard deviation of $0.35. Assume that the distribution is normal. If a worker at this fast food restaurant is selected at random, what is the probability that the worker earns more than $6.25 an hour?© BrainMass Inc. brainmass.com March 4, 2021, 5:41 pm ad1c9bdddf
First calculate the z-score
z = (X - mu)/sigma = (6.25 - 5.85)/0.35 = 1.1428
What is the p that z ...
Probability within a normal distribution is determined. The probability that a worker earners more than $6.25 is determined.
