Suppose there is 1 dependent variable (dissolved oxygen, Y) and 3 independent variables (water temp X1, depth X2, and hardness of water X3). Below is the result of the multiple linear regression.Which of the following statements is TRUE? Both intercept and water temperature are the significant predictors of the amount of dissolved oxygen. If all other predictor variables are held constant, the amount of dissolved oxygen decreases on the average by 0.15 for every 1 unit increase in depth. Hardness is also a significant predictor of the amount of dissolved oxygen since its coefficient -0.04 is less than 0.05. The intercept has strong linear relationship with the amount of dissolved oxygen.

An editorial in The New York Times on Sunday, June 4, 2011 discussed the redesigned fuel economy stickers to be required on new cars starting in 2013. Consider a new midsize Ford Fusion S model. At $4-a-gallon gas, annual fuel costs would be about $2,200 for 15,000 miles driven. ... And that’s for a car with a rated mileage of 34.9 m.p.g. (actual highway mileage, as with all vehicles, is lower, in this case about 27 m.p.g.). Industry clearly needs to do better. Did the Times use the rated or the actual mileage in its computation? In Canada, some multi-lane highways have a speed limit of 110 km/hour. Convert this speed to miles per hour, so you'll know how fast you may drive in Canada.
