Question: The temperature dataset on the companion website gives y 5 mean April temperature (Fahrenheit) and x = geographic latitude for 20 U.S. cities. The simple linear regression equation for the sample is y^ = 119 - 1.64x.
a. The value of latitude for Pittsburgh is 40. What is the predicted April temperature for Pittsburgh?
b. The mean April temperature for Pittsburgh is 50. What is the residual for Pittsburgh?
Choose a point at random in the square with sides 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1. This means that the probability that the point falls in any region within the square is the area of that region.
Calculate the predicted value of Y when the value of X=40? Test whether the correlation coefficient r= 0.57956 is significant or not? Test whether the slope of the regression coefficient is significant or not? Calculate the regression line for the gi..
