QUESTION 12 Which of the following distribution's shape does not change with degrees of freedom? a. Studentt b.z c. Chi-square d.F e. the distribution shape does not depend on degrees of freedom.
Let t be a t-random variable. P(t>a) 0.025 and 12 degrees of freedom. Find a. P(t < a) 0.05 and 21 degrees of freedom. Find a. P(-a < t<a) = 0.95 and 27 degrees of freedom. Find a. For 15 degrees of freedom, find P(t < 1.753) For 22 degrees of freedom, find P(-2.074 < t < 2.074). Use Excel function =t.dist to find P(t<-2.86) with df 25 Use Excel function =t.dist.rt to find P(t > 1.33) with df 29...
