ISYE 6414 Midterm Prep Questions and Answers Graded A+ We can assess the constant variance assumption in linear regression by plotting the residuals vs. fitted values. True If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the two corresponding means are plausibly equal. True The assumption of normality is not required in linear regression to make inference on the regression coefficients. False (Explanation: is required) We cannot estimate a multi...

The prediction interval of one member of the population will always be larger than the confidence interval of the mean response for all members of the population when using the same predicting values. (T/F) - correct answer True. See 1.7 Regression Line: Estimation & Prediction Examples "Just to wrap up the comparison, the confidence intervals under estimation are narrower than the prediction intervals because the prediction intervals have additional va...

James participated in an archery competition. He was allowed four attempts and was supposed to hit the bullseye in the center of the board. If the figure shows the positions of James' arrows, which of the following would best classify the arrangement of arrows? ● Low accuracy and high precision ● High accuracy and low precision ● High accuracy and high precision ● Low accuracy and low precision RATIONALE The arrows are close to the center so they are accurate and they are also ...

CIC SURVEILLANCE AND EPIDEMIOLOGIC INVESTIGATION EXAM QUESTIONS AND ANSWERS Rationale: A Type I error occurs when one rejects the null hypothesis (H0) when it is true. This is also called a false-positive result (as we incorrectly conclude that the research hypothesis is true when in fact it is not). The p value or calculated probability is the estimated probability of rejecting the null hypothesis of a study question when that hypothesis is true. 14. On a normally distributed data set, wh...

In logistic regression, we model the__________________, not the response variable, given the predicting variables. - Answer-probability of a success g link function - Answer-link the probability of success to the predicting variables 3 assumptions of the logistic regression model - Answer-Linearity, Independence, Logit link function Linearity assumption for a Logistic Model - Answer-Similar to the regression model we have learned in the previous lectures, the relationship we assume now, bet...
