Question

Consider the hypothesis test Ho:H1 I| = 7.8 and I2 = 5.6 and that.s? = 42 against Hy: 141 > M2. Suppose that sample sizes are my = 15 and n2 = 15, that +and s? =9. Assume that of = o; and that the data are drawn from normal distributions. Use a = 0.05. Test the hypothesis and find the P-value. a. b. What should the decision for the test be? Reject the null hypothesis or Fail to reject the null hypothesis. What is the P-Value for the test? Round your answer to three decimal places (e.g., 98.765).

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.
