Your boss shows you the ER model that he has spent a couple days to finish. You are asked to make some comments ont How will you use your skills from this course to modify and/or improve this ER model? (1) If you decide to modify the ER model, draw the new diagram and EXPLAIN in detail why you want...

3. A car manufacturer offers a 5yr/Unlimited km warranty on one of its models. Historically, 8% of cars sold will require repairs under the terms of this warranty. Suppose a dealer sells 190 cars of that model and let X be the number of those cars that will require service under the terms of the warranty. (a) A suitable probability...

Question 3. Multiple linear regression [6 marks] Create a multiple linear regression model, including as explanatory variables wt, am and qsec. To run multiple linear regression to predict variable A based on variables B, C and D you need to use R’s linear model command, Im as follows, storing the results in an object I'll call regm. regm <- lm...

Problem 7. Consider the simple linear regression model Y1 = Bo + BiX; +€; for i=1,2,...,n where the errors Eį are uncorrelated, have mean zero and common variance Varſei] = 02. Suppose that the Xį are in centimeters and we want to write the model in inches. If one centimeter = c inch with c known, we can write the...
