Question

Find the value of t for a t-distribution with 12 degrees of freedom such that the area between −t and t equals 90%. Round your answer to three decimal places, if necessary.

Answer 1

To find the value of t for a t-distribution with 12 degrees of freedom such that the area between −t and t equals 90%, we can use a t-table or a calculator.

Step-by-step explanation:

To find the value of t for a t-distribution with 12 degrees of freedom such that the area between −t and t equals 90%, we can use a t-table or a calculator. In this case, we'll use the calculator function invT(0.95, 12). Plugging in the values, we find that the t-value is approximately 1.356.
