Question

HELP WITH PROB AND STATS

Use the given data to find the best predicted value of the response variable.

Six pairs of data yield r= 0.344 and the regression equation y = 5x + 2. Also, y = 18.3
What is the best predicted value of y for x = 5? Use a = 0.05.

Answer 1

Sub in x = 5 into the equation y = 5x + 2. If you do that you should get a y-value of about 27.
