You need to determine the y-intercept of the regression line for a data set. The sums of the variables and the slope are given below.
Find the y-intercept, only. round to the thousandths place
Homework Answers
Answer
we have the following data values
Formula for the y intercept(b) is given as
![b= [(sum y *sum x^2)-(sum x * sum xy)]/[(n*sum x^2)-(sum x)^2]](http://img.homeworklib.com/questions/30d6ec60-2abe-11eb-8f29-3f704962e8e6.png?x-oss-process=image/resize,w_560)
setting the given values, we get
this gives us
intercept b = 17732/316 = 56.114 (rounded to thousandths place)
