Question
The number of motor vehicles registered in millions in the US has grown as follows:
Year: 1940, 1945 1950, 1955, 1960, 1965, 1970, 1975, 1980, 1985
Vehicles: 32.4, 31.0, 49.2, 62.7, 73.9, 90.4, 108.4, 132.9, 155.8, 171.7
(Where Year = X and Vehicles = Y)
Use logarithms to transform the data into a linear association. White the equation of the LSRL. Your answer should have logs in it. Remember to define any variables.
The answer is log y-hat = -2.4281 + 2.4208 log(year) where y-hat=vehicles-hat.
I am aware that the values come from the calculator, but I need help into figuring out exactly what I put into the calculator. I have already put the data in list 1 and list 2 and I'm pretty much stuck here.
Explanation / Answer
Clear out list 3 and move the cursor up to highlight L3, then press ENTER. Type log(L1) and press ENTER. Then do the same thing in L4, but enter log(L2). Now run LinReg on L3 and L4 and you'll get your answer. Hope this helps you.
