a. Calculate the standard error of the estimate.
b. Estimate the strength of the linear relationship between x and y.
Solutions
Expert Solution
a)
| SSE =Syy-(Sxy)2/Sxx= | 22,977.1253 |
| error Variance σ2 = | s2 =SSE/(n-2) | = | 2297.7125 | |
| standard error of estimate = | se =√s2 | = | 47.9345 | |
b)
| correlation coefficient r= | Sxy/(√Sxx*Syy) = | 0.9605 | ||
as correlation coefficient is positive and closer to 1, this tells us that there is a strong positive linear relationship between x and y.
