For each of these scenarios, use a graphing utility to create a scatterplot of the data, and then answer the questions that follow. 1. The National Weather Service uses a chart to determine the wind chill factor at various wind speeds. Wind chill is the cooling effect caused by wind blowing on a surface. This phenomenon explains why you can feel colder on a windy day than on a calm day, even if both days have the same air temperature. The following table shows the air temperature in degrees Fahrenheit ("F) and the corresponding wind chill factor (the temperature in degrees Fahrenheit that it feels like) for a wind speed of 20 miles per hour (mph): Air Temperature (°F) Wind Chill Factor ("F) (a) Determine the equation of the regression line. 40 30 35 24 30 17 25 11 20 4 15 -2 (b) What is the slope of the regression line and what does it mean in the context of the problem? (c) What is the dependent variable axis intercept and what does it mean in the context of the problem? (d) Use the equation of the regression line to estimate the wind chill factor for a 32°F day with a wind speed of 20 mph. Show the work that leads to your answer.
