Consider a t distribution with 7 degrees of freedom.
Compute P(-1.29 < t < 1.29). Round your answer to at
least three decimal places.

Using a TI-84 Plus calculator:
P(-1.29 < t < 1.29) = tcdf(-1.29,1.29,7) = 0.7620

Consider a t distribution with 18 degrees of freedom. Find the value of c such that P(t<= c) = 0.05. Round your answer to at least three decimal places.
Find the t-value with df = 18 and a left tail of 5%
invT(0.05,18) = -1.7341
