What is the equation of the regression line?

Select the correct answer below:

yˆ=−1.821x+17.1

yˆ=−1.821x+61.6

yˆ=10.912x+61.6

yˆ=10.912x+17.1

Answer #1

The statistical software output for this problem is:

Hence,

Equation of regression line will be:

**y = -1.821x + 61.6**

**Option B** is correct.
