Question

Use the appropriate normal distribution to approximate the resulting binomial
distribution:

The Colorado Mining and Mineral Company has 1000 employees engaged in its mining operations. It has
been estimated that the probability of a worker meeting with an accident during a 1-yr period is 0.067. What
is the probability that at least 50 workers will meet with an accident during the 1-yr period?

A) 0.8665

B) 0.9089

C) 0.9864

D) 0.3827

E) 0.6548

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.
