Say that global temperatures could change over the next several decades and you have it on good advice that the change (in degrees Celsius) is equal to the percentage change in CO^2 use in the USA times .2 and then you would add the percentage change in CO^2 use in the rest of the world times .8. Over the time period the percentage change in CO^2 use in the USA is expected to fall with a uniform distribution between -10 and -6 percent and the percentage change in CO^2 use in the rest of the world has a normal distribution with mean of 2.2 percent increase and a standard deviation of .1. (Think of 2.2 percent, for example, as 2.2 and not 0.022 in this instance.)

1. Simulate 1000 trials of global temperature change.
2. In your simulation, what is the probability that global temperatures will DECLINE?

*Please attach the Excel file you use for the simulation. Plus, when you answer question 2 please write a complete sentence answer. Simply highlighting an answer will not be sufficient.
