Question: Calculate the following quantities using Excel. a. Find the value of x such that P(t10 > x) = 0.75, where t10 has a t distribution

Calculate the following quantities using Excel.
a. Find the value of x such that P(t10 > x) = 0.75, where t10 has a t with 10 degrees of freedom.
b. Find the value of y such that P(t100 > y) = 0.75, where t100 has a t with 100 degrees of freedom. How do you explain the difference between this result and the result obtained in part a?
c. Find the value of z such that P(Z > z) = 0.75, where Z is a standard normal random variable. Compare this result to the results obtained in parts a and b. How do you explain the differences in the values of x, y, and z?
