Quizplus · Accepted Answer

For a t-distribution with 6 degrees of freedom (df = 6) and a middle area of 0.99, the two t-values that divide the curve into the specified areas are found using t-distribution tables or software for the 0.005 (0.5% in each tail since 1 - 0.99 = 0.01 and 0.01/2 = 0.005) significance level. The correct values are -3.707 and 3.707, which correspond to the critical t-values for a two-tailed test with a total area of 1% outside the middle 99% area.
