3. A researcher estimates a regression model that contains three variables and a constant, based on a random sample of 30 observations. The researcher suspects a problem with positive autocorrelation and wants to test for its existence. She decides to use a 5% level of significance specify the conditions under which she will draw the possible conclusions available with this test, that is what are the appropriate...

11. Using Excel - Scatter diagrams, estimated regression equations, and trendlines Suppose a company records data on sales calls, induding the length of each call and whether a sale was made. The manager is interested in determining whether there is a relationship between the average time spent per call and the number of sales made by each employee, so she obtains the average call length and the total number of sales over a 2-week period for a...
