This one really confuses me. Please help!
1) Find the correlation coefficient and round it to three decimal places.
2) Based on the data, calculate the regression line and give it in the formy=mx+by=mx+b . Round each value ofmm andbb to three decimal places.
3) Predict what value (on average) for the response variable will be obtained from a value of 104.69 as the explanatory variable and interpret what it means in context. Instead, use your equation from #2 and algebra to find your prediction and round to 2 decimal places.
Show your work/calculations and round to 2 decimal places. Explain in a complete sentence.
