Suppose that you have decided to buy an ice cream truck to go into the ice cream business this summer instead of getting a summer job. You collected data every day last summer while working for an ice cream company about the temperature (in F) and sales (in dollars) for that day as a way to research for your new business. You decided to fit a regression line and get the following based off of your data

Sales = -762 + 18.53*Temperature R2 = 47.1%

2. What is the correlation between these two variables?

a) R= -0.6862944

b) R= 0.6862944

c) R= 0.221841

d) R= -0.221841
