Time is in seconds, Money is in dollars, Evil is in laughs, Love is in Heartbeats, War is in
kills, and Peace is in minutes.

Explain the effect on Time of:
Money: As money increases by 1 dollar Time increases by 1.0292
Evil: As evil increases 5% Time increases by 0.1086
5.124578*log(1.05) = 0.1086
Love: We cannot show that love affects the time
War: We cannot show that war affects the time
Peace: If peace goes up by 10% then time goes down by 0.05131
-1.2396*log(1.10) = -.05131

Size is in cubic centimeters, Age is in years, Weight is in pounds, Temperature is in
degrees Fahrenheit, Height is in inches, Cost is in dollars, and Distance is in miles
The regression equation is
Log(Size) = 28.6 + 0.0292 Age - 1.124 Weight - 1.69
log(Temperature) + 1.02 log(Height) + 2.24 log(Cost) 0.334 log(Distance)

What is the effect on Size of:
Age: As age increases by one year the size increases by 7%
10^(0.0292) = 1.07 = 1+.07
Weight: As weight increases by one pound the size decreases by 92.5%
10^(-1.124) = 0.075 = 1-.925
Temperature: As temperature increases by 7% the size will decrease by 11%
10^(-1.691*log(1.07)) = 0.89 = 1 – 0.11
Height: We cannot show that height affects the size
Cost: As cost increases by 5% the size increases by 11.5%
10^(2.239*log(1.05)) = 1.115 = 1+0.115
Distance: As distance increases by 25% the size will decrease by 7.2%
10^(-.334*log(1.25)) = 0.928 = 1 – 0.072
