Compute P(-1.25 < t < 1.25) Round your answer to at least three decimal places.p(-1.25 < t < 1.25) = ?(b)Consider a t distribution with 6 degrees of freedom. Find the value of c such that p= (t ≥ c)=0.01 . Round your answer to at least three decimal places.c=

Answer 1

Using a Student's t-Distribution calculator we find that

a) P(-1.25 < t < 1.25) =0.757

b)he value of c such that p= (t ≥ c)=0.01 is 3.14267.
