Question

The following table shows the hot dogs bought from a street vendor over the course of eight days ("Demand"). Also shown is the temperature for each day in degrees Celsius. Complete parts a and b below. nbsp Temperature left parenthesis degrees Upper C right parenthesis nbsp Temperature °C 22 11 24 16 8 14 17 19 Demand 45 29 35 40 16 21 44 31 a. Calculate the slope and y-intercept for the linear regression equation for these data. ModifyingAbove y with caret equals nothing plus left parenthesis nothing right parenthesis xy=+x (Round to two decimal places as needed.) b. Predict the demand for hot dogs on a day with a temperature of 23 degrees Upper C The predicted demand for hot dogs on a day with a temperature of 23degrees Upper C is nothing. (Round to the nearest integer as needed.)
