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 5.6 y-257 SSy-248 ss,x-6.4 SSyy-69010 Find the coefficient of determination and interpret its value. 0.8607; about 86% of the variation in the y values is explained by the model. 0.1393 the model predicts y 14% of the time 0.1393 about 14% of the variation in the y values is explained by the model. 0.3732 about 37% of the variation in the y values is explained by the model. None of these

Explanation / Answer

The statistical software output for this problem is:

Simple linear regression results:
Dependent Variable: Y
Independent Variable: X
Y = 40 + 38.75 X
Sample size: 10
R (correlation coefficient) = 0.3731691
R-sq = 0.13925518
Estimate of error standard deviation: 86.16844

Hence,

R-sq = 0.1393

Option C is correct.
