Question 932588: The amount of time that office workers at Company XYZ spend on the computer each workday is normally distributed with a mean of 3.1 hours and a standard deviation of 0.5 hours. Find the percentage of office workers at company XYZ who spend less than 4.1 hours on the computer per work day. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! mean of 3.1 hours and a standard deviation of 0.5 .
.........
P(x < 4.1) = p (z < 1/.5) = normalcdf(-100, 2) = .9772 0r 97.72%
..........
Area under the standard normal curve to the left of the z = 2 is the p-value = P(z < 2)
Note: z = 0 (x value: the mean) 50% of the area under the curve is to the left and 50% to the right
