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.
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.
p(-1.29 < t < 1.29) =
c =

Step-by-step explanation:

Given that there is a t distribution with 7 degrees of freedom.

P(-1.29 < t < 1.29)=1-0.2380

=0.7620

b) Now there is a different t distribution with 18 df.

When

c=-1.733

i think 1: 2

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
