Question

Consider the following competing hypotheses and relevant summary statistics:

H₀: σ21/σ22�12/�22 = 1
H_A: σ21/σ22�12/�22 ≠ 1

Sample 1: x¯�¯ ₁ = 45.3, s21�12 = 17.6, and n₁ = 6
Sample 2: x¯�¯ ₂ = 48.1, s22�22 = 11.4, and n₂ = 4

Assume that the two populations are normally distributed. (You may find it useful to reference the appropriate table: chi-square table or F table)

a. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)

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.
