People have been using Cameras for private daily use since the1880s and the first Kodak camera cost a lot of money in those days.Today we wish to see if the size of the camera can be used topredict the cost. The data is given below:
Y = cost in dollars X = weight in ounces y {300, 250, 350, 400,150, 180, 140, 300, 300, 200} X {6, 5, 7, 5, 6, 6, 4, 6, 6, 5} Thefollowing information is available for you to use in the analysisof this topic. n=10 x̄= 5.6 ȳ= 257 SSxy = 248 SSxx = 6.4 SSyy =69010
Find the least squares prediction equation. a)Ŷ = -300 + 100X1b)Ŷ = 0 + 50X1 c)Ŷ = 40 + 38.75X1 d)none of these
