Question

Margot is studying the yield of bushels of wheat in comparison to the amount of rainfall, in inches, that occurs. She finds the linear regression equation to be y = 47.3 +0.78x. What does 47.3 mean in the context of the problem?

Answer 1

notice how 47.3 is the y-intercept, or the value of the y when x = 0

in the context of the problem, since y represents yield of wheat bushels in terms of x (the inches of rainfall), 47.3 is the yield of bushes at 0 inches of rain.
