The average August temperatures (y) and geographic latitudes (x) of 12 cities in the United States were studied. The regression equation for these data is Temperature 90.4 -1.23*(latitude) What is the slope of the line? Interpret the slope The latitude changes by 90.4 for every change of temperature The temperature changes by 1.23 for every change of one latitude A one degree increase of temperature is a 1.23 drop in latitude O To get 90.4 more degrees of temperature you must climb one degree of latitude If you climb 90.4 degrees of latitude you will get an increase of one degree in temperature O An increase of one latitude is a 1.23 drop in temperature Estimate the mean August temperature for a city with latitude of 22. Use 2 decimal places San Francisco has a latitude of 39. What would you predict for the mean August temperature of San Francisco? Use 2 decimal places Given that the mean August temperature in San Francisco is actually 69 calculate the residual (prediction error) for San Francisco It should be observed minus predicted. If you do it wrong your answer have the positive and negative switched Use 2 decimal places The latitude at the equator is 0. Estimate the average August temperature at the equator. Use 1 decimal place
