For a t distribution with 12 degrees of freedom, the area between - 2.6810 and 2.1788 is 0.980.

Question

Quizplus · Accepted Answer

The t-distribution is symmetric around zero, so the areas to the left of -2.6810 and to the right of 2.1788 do not mirror each other exactly in terms of distance from the center. Therefore, without specific values from a t-distribution table or software, the exact area between these two t-values cannot be accurately stated as 0.980 without calculation. The given values suggest a high coverage area, but without precise calculation, the exact area cannot be confirmed as 0.980.
