Question

Find the value of t for a t-distribution with 3 degrees of freedom such that the area to the left of t equals 0.10.

Possible Answers:
A. 5.841
B. 4.541
C. -2.333
D. -1.638

Answer 1

Here we have to find the t table value for degrees of freedom = 3 and area to the left of t equals 0.10

From table we get P(t > 1.638) = 0.10

so P(t< - 1.638 ) = 0.10 ................Since t distribution is symmetric.

So Value of t = -1.638

So Answer is d) -1.638
