Consider the tale of the physicist who is ticketed for running a red light andargues that, because he was approaching the intersection, the red light wasdoppler shifted and appeared green. the speed limit is 0.55c. should he receivea ticket for running the red light, a ticket for speeding, or no ticket at all? [hint: λred= 650 nm,λgreen= 530 nm; you may use the formulas in chapter1.14 of the textbook]

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
