A) ±2.763
B) ±2.756
C) ±2.467
D) ±2.462

Question

Quizplus · Accepted Answer

For a two-tailed test at the α = 0.01 level of significance with a sample size of n = 29, the degrees of freedom (df) would be n - 1 = 28. Using the t-distribution table, the critical value closest to a 0.01 level of significance (0.005 in each tail for a two-tailed test) for 28 degrees of freedom is ±2.763.
