Question

The following table presents the test scores on the first (x) and second (y) exam in a Biology class. The least-squares regression line is in the form y = b_0 + b_1x. Compute the value of b_1. That is, compute the slope. Write only a number as your answer. The following table number of absences (x) and the grade earned on the first exam (y) for a Statistics class. The least-squares regression line is in the form y = b_0 + b_1x. Compute the value of b_0. That is, compute the d. Write only a number as your answer.

Explanation / Answer

Using the data and technology we find the regression line

y=-3.646+1.211x

So, the slope is 1.21

-----------------

Using the data and technology we find the regression line

y=104.17-6.38x

So, the intercept is 104.17
