Questions 1-4 use the following scenario:
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
R 47.1%
