Question

People have been using Cameras for private daily use since the 1880s 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 to predict 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} The following information is available for you to use in the analysis of this topic. n=10 x= 5.6 = 257 SSxy = 248 SSxx = 6.4 SSyy = 69010 Calculate SSE?

a)78620 b)729500 c)59400 d)none of these

Explanation / Answer

We know that SSE = SST - SSR

From the given data we have SST = 69010 and SSR = 9610

So we get SSE = 69010 - 9610 = 59400

Hence c) 59400 is the correct answer.

Hope this will help you. Thank you :)
