Given a sample with r = -0.541, n = 20, and ? $\alpha$ = 0.01, determine the standardized test statistic t necessary to test the claiclaim $\varrho$ = 0. Round answers to three decimal places.
A)-2.729
B)-5.132
C)-4.671
D)-3.251

Question

Quizplus · Accepted Answer

The correct choice is A because the standardized test statistic t is calculated as t = r * sqrt(n-2) / sqrt(1-r^2) = -0.541 * sqrt(20-2) / sqrt(1-(-0.541)^2) = -2.729.
