Given the following information, N = 49, $\bar { x }$ = 50, s = 7 H₀:$\mu$ > 52 H_a: $\mu$< 52 The test statistic is A) 2. B) -2. C) 1. D) -1.

Quizplus · Accepted Answer

The test statistic is calculated using the formula: $ t = \frac{\bar{x} - \mu_0}{s/\sqrt{N}} $. Substituting the given values: $ t = \frac{50 - 52}{7/\sqrt{49}} = \frac{-2}{1} = -2 $.
