Hello all! Just a question for those of you that are mathematically inclined.
Use the given data to find the best predicted value of the response variable.
Six pairs of data yield r = 0.444 and the regression equation y-hat = 5x + 2 Also, the mean of all dependent variables (y with a bar over the top) is 18.3 What is the best predicted value of y for x = 5 ?
I thought it was as simple as plugging in X... sadly, it isn't. :/ Anyone know what I could be doing wrong?
