a. use Excel/XLSTAT to calculate p-value for the coefficient of X1. Is it significant? α = 0.05. Next, the T table and interpolate the p-value

b. use Excel/XLSTAT to calculate p-value for the coefficient of X2. Is it significant? α = 0.05. Next, the T table and interpolate the p-value

c. use Excel/XLSTAT to calculate p-value for the coefficient of X1. Is it significant? α = 0.05. Next, the T table and interpolate the p-value

d. perform an F test

Does the input requirement set V (y) = {(x1, x2, x3) | x1 + min {x2,...

Does the input requirement set V (y) = {(x1, x2, x3) | x1 + min {x2, x3} ≥ 3y, xi ≥ 0 ∀ i = 1, 2, 3} corresponds to a regular (closed and non-empty) input requirement set? Does the technology satisfies free disposal? Is the technology convex?

(a) Consider three positive integers, x1, x2, x3, which satisfy the inequality below: x1 +x2 +x3 =17. (1) Let’s assume each element in the sample space (consisting of solution vectors (x1, x2, x3) satisfying the above conditions) is equally likely to occur. For example, we have equal chances to have (x1, x2, x3) = (1, 1, 15) or (x1, x2, x3) = (1, 2, 14). What is the probability the events x1 +x2 ≤8occurs,i.e.,P(x1 +x2 ≤8|x1 +x2 +x3 =17andx1,x2,x3 ∈Z+)(Z+...
