Freshcrim specializes in the sales of ice cream from street trolleys in the centers of many cities. Some factors
that may determine the sales of ice cream are: the atmospheric temperature, the location of the trolley, the
rain and the humidity. However, there exists a hypothesis that the sales of ice cream during the summer are
significantly
atmospheric temperature and Y : the sales. They considered the month of July of this year in a random
sample of 30 cities. For each city in the sample, let x be the mean temperature in degrees Fahrenheit and y
the mean sales per day in dollars per 100,000 residents. The data are given below. A regression model was
run, with Y as the dependent variable and X as the independent variable.
