The average hourly wage of employees of a certain company is $9.83. Assume the variable is normally distributed. If the standard deviation is $4.58, find the probability that a randomly selected employee earns less than $5.43.
---------------------------------
Find the z-value of 5.43
-----
z(5.43) = (5.43-9.83)/4.58 = -0.9607
-----------------------------------
P(x < 5.43) = P(z < 0.9607) = 0.1684
