Consider the following competing hypotheses and relevant summary statistics: (You may find it useful to reference the appropriate table: chi-square table or Ftable) Ho: 01/02 1 HA: 02/01 Sample 1: s= 1,315, and n₁ = 17 Sample 2: s2 = 1,523, and n2 = 19 a. Calculate the value of the test statistic. (Round your answer to 3 decimal places.) Test statistic b-1. Find the p-value. O p-value < 0.01 O 0.01 ≤ p-value < 0.025 O 0.025 ≤ p-value < 0.05 O 0.05 ≤ p-value < 0.10 O p-value ≥ 0.10 b-2. At a = 5%, what is your conclusion? O Reject Ho; we can say that variance 1 is lower than variance 2. O Reject Ho; we cannot say that variance 1 is lower than variance 2. Do not reject He; we can say that variance 1 is lower than variance 2. O Do not reject Ho; we cannot say that variance 1 is lower than variance 2.
