Approximate the area under the t - curve, with degrees of freedom 29, to the right of t = 2.462     .005     .10     .25     .01

Consider the value of t such that 0.05 of the area under the curve is to the right of t. Step 2 of 2 :   Assuming the degrees of freedom equals 24, select the t value from the t table.

Find the indicated z-score shown in the graph to the right. Area = 0.0681 O z=? The z-score is |. (Round to two decimal places as needed.)

Use the table to find the area to the right of t = 1.717 with 22 degrees of freedom. Area to the right Degrees of Freedom 0.20 0.10 0.05 0.025 0.01 0.005 21 0.859 1.323 1.721 2.080 2.518 2.831 22 0.858 1.321 1.717 2.074 2.508 2.819 23 0.858 1.319 1.714 2.069 2.500 2.807 24 0.857 1.318 1.711 2.064 2.492 2.797 25 0.856 1.316 1.708 2.060 2.485 2.787 According to the table, the area to the right of t = 1.717 is Now find the area to the left of t = 1.717, rounding the result to two decimal places. (area to the left of t = 1.717) = 1 – (area to the right oft = 1.717) - = 1 -
