It is known that, nationally, doctors working for HMOs average 13.5 years of experience in their specialties, with a standard deviation of 7.6 years. The distribution is a normal distribution. The executive director of an HMO in a western state is interested in determining whether or not its doctors have less experience than the national average. A random sample of 64 doctors from the HMO shows a mean of only 10.9 years of experience. State the research and null hypotheses to test whether or not doctors in this HMO have less experience than the national average at α = .05.

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.
