Problem-
The average hourly wage of workers at a fast food restaurant is $6.50/hr with a standard deviation of $0.45. Assume that the distribution is normally distributed. If a worker at this fast food restaurant is selected at random, what is the probability that the worker earns more than $6.75?
Additional information-
This problem related to Basic Statistics and it is about a study on the average wages of a fast food restaurant worker. The problem is about picking up a random worker whose salary is above the average wage.
