Solve using R Caculator

The average hourly wage for manufacturing workers in the United States is $16.17 per hour, with a standard deviation of $1.42. Assume the data is normally distributed. What is the probability that a randomly chosen manufacturing worker makes more than $15.95 an hour?

List the z-scores needed to calculate the result. If there is more than one z-score, separate the values with a comma.

There is a ___ chance that a randomly chosen manufacturing worker makes more than $15.95 per hour.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
