Textbook Question

Chapter 10, Problem 21E

Refer to Table 10–4 and the example just completed. With n = 100, σ = 400, x ¯ c = 9 , 922 and μ₁ = 9,880, verify that the probability of a Type II error is .1469.

TABLE 10–4 Probabilities of a Type II Error for μ₀ = 10,000 Pounds and Selected Alternative Means, .05 Level of Significance

Chapter 10, Problem 21E, Refer to Table 104 and the example just completed. With n = 100, = 400, xc=9,922 and 1 = 9,880,

*It is not possible to make a Type II error when μ₁ = μ₀.

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.
