MAT 150 Exam Questions and Answers | Latest 2023/2024 | Straighterline (GRADED). What is the critical value of F at the 5% level of significance? Select one: a. 3.29 b. 3.68 c. 3.59 d. 3.20 Feedback There are three treatments and a total of 18 observations, so k = 3 and n = 18. The treatment degrees of freedom are k - 1 = 3 - 1 = 2, and the error degrees of freedom are n - k = 18 - 3 = 15. Therefore, the F-distribution would have 2 degrees of freedom in the numerator and 15 degrees of ...

If Claim Counts are Poisson(m), and d = probability of reporting in first period What is the Bayes Reserve? Answer - R(x) = mu(1 - d) List the 3 Special Cases for Brosius Least Squares Answer - y = a + bx | Least Squares | Restriction y = bx | Chainladder | a=0 y = a + x | Bornhuetter-Ferguson | b=1 y = a | Budgeted Loss | b=0 Claim Counts are NegBin(r, p) d is the probability of reporting in the first period x is the actual reported in the first period What is the Bayes Reserve? A...

ISYE 6414 Final Exam Review; Questions and Answers 100% Verified Least Square Elimination (LSE) cannot be applied to GLM models. Answer-False - it is applicable but does not use data distribution information fully. In multiple linear regression with idd and equal variance, the least squares estimation of regression coefficients are always unbiased. Answer-True - the least squares estimates are BLUE (Best Linear Unbiased Estimates) in multiple linear regression
