Part 3 Linear Regressions Free Worksheet And Solutions Concept check solutions. 1) the point (4, 140) is an outlier, potentially an exceptional employee that is compensated highly for their work despite having less experience than others. 2) 0.9 (the data is fairly linear and positively correlated) 3) y = 5.25x 58. Worksheet page 1. students will write a linear regression equation and use the equation to solve problems like: the table shows the amount of soft drink and that is given to the competitors in every 2 hours following a 12 ml. it seems that the rate of decrease of the drink is approximately proportional to the amount remaining.
Part 3 Linear Regressions Free Worksheet And Solutions There is not a significant linear correlation so it appears there is no relationship between the page and the amount of the discount. page 200: 14.39; no, using the regression equation to predict for page 200 is extrapolation. \(\text{slope} = 0.01412\) as the page number increases by one page, the discount decreases by $0.01412. 1. the simple linear regression model 1.1. problem: slr model 2. estimates and plug in prediction 3. con dence intervals, prediction, and hypothesis tests 3.1. problem: the shock absorber data 3.2. problem: predictive interval for the shock data 3.3. problem: beta for fidelity funds. Graph of linear regression in problem 2. a) we use a table to calculate a and b. we now calculate a and b using the least square regression formulas for a and b. b) now that we have the least square regression line y = 0.9 x 2.2, substitute x by 10 to find the value of the corresponding y. 3 = 0 vs h a: 2 and or 3 ≠ 0 complete model: y = 0 1 x 1 2 x 2 3 x 3 anova df ss ms f p value regression 3 2470.4 823.5 76.9 .0000 residual 21 224.7 10.7 total 24 2695.1 reduced model: y = 0 1 x 1 df ss ms f p value regression 1 2394.9 2394.9 183.5 0.0000 residual 23 300.2 13.1 total 24 2695.1.
