WebMar 5, 2015 · MX(t) = (q1 + p1et)n1, MY(t) = (q2 + p2et)n2. Since X and Y are independent. MX + Y(t) = MX(t) ⋅ My(t) = (q1 + p1et)n1 ⋅ (q2 + p2et)n2. We see that we cannot express it in the form (q + pet)n and thus by uniqueness property of MGF X + Y is not a binomial variate. However if we take p1 = p2 = p then we have: Webn1 = 50 n2 = 60 x1 = 21 x2 = 19 s1 = 1.5 s2 = 1.9 2) 3) A random sample of 15 statistics textbooks has a mean price of $105 with a standard ... distribution that should be used to calculate confidence intervals is 29) ... 43) Find p and q, if X1 = 11, n1 = 30, X2 = 28, and n2 = 80. 43) 44) If the correlation coefficient is 0.790, what is the ...
