4 Assumptions of OLS correct answers -no serial correlation -no heteroscedasticity -no multicollinearity -normality no serial correlation and test correct answers -significant relationship between a variance and itself at diff time points (repeated variable) -test with durbin-watson test. range between 0 (extremely positive) and 4 (extremely negative. 1.5-2.5 good no heteroscedasticity and test correct answers -variability of a variable is highly scattered -test with breusch-pagan. P...

2a) Let income denote the person's income and age denote the persons age. We would like to run an OLS regression on the equation BMI=B0+B1fast+B2income+B3age+U. Write down all the assumptions that guarantee that the OLS estimators of the coefficients of this equation are unbiased correct answers 1)Linearity- E[U|fast, income, age]=0, The expected value of y is linear in X1,X2,X3 2)Exogeneity- E[U|fast, income, age]=0, unobservables are constant and do not effect BMI 3)Random Sampling- The dat...

Six Sigma Black Belt Session 8 Questions and Answers Already Passed A Lean Six Sigma team is trying out a new forming tool to reduce variability in a process that creates hamburgers patties in a fast food restaurant. One of the significant dimensions has a process standard deviation of 0.35 mm. The team needs to know how many samples to collect in order to achieve an estimate of the mean with precision of + or - 0.15 mm, with 95% confidence. What sample size is required to meet this goal...
