Question

11. It is known that the wages of weekly workers in a particular industry follow the Normal distribution
with mean R294 and standard deviation R43. A random sample of 1 366 workers is selected.
a) How many workers do you expect will earn more than R255 (rounded off to zero decimals)?
b) How many workers do you expect will earn less than R315 (rounded off to zero decimals)?
c) How many workers do you expect will earn between R196.82 and R336.14 (rounded off to zero
decimals)?
d) How many workers do you expect will earn between R196.82 and R230.79 (rounded off to zero
decimals)?

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.
