The following table shows the hot dogs bought from a street vendor over the course of eight days ("Demand"). Also shown is the temperature a. Calculate the slope and y-intercept for the linear regression equation for these data. y = [ + () x (Round to two decimal places as needed.) b. Predict the demand for hot dogs on a day with a temperature of 16 C. The predicted demand for hot dogs on a day with a temperature of 16"C is ]. (Round to the nearest integer as needed.)
