The wind chill factor depends on wind speed and air temp. This
data represents the wind speed (in miles per hour) and wind chill
factor at an air temp. of 15 degrees F. Wind speed(x) 5, 10, 15,
20, 25, 30, 35 Wind chill(y) 12, -3, -11, -17, -22, -25, -27
Compute the least squares regression line and correlation
coefficient for this data. Predict the wind chill for a wind speed
of 50 miles per hour. Determine the wind speed...
