Consider the following competing hypotheses and relevant summary statistics: H₀: 21/2212/22 = 1 H_A: 21/2212/22 1 Sample 1: xx ₁ = 48.5, s21s12 = 18.7, and n₁ = 10 Sample 2: xx ₂ = 50.2, s22s22 = 12.9, and n₂ = 8

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