the answer is y-7/12=-1/11(x-7/12) but I dont know why
5) Let X and Y have joint probability density function Graph the support of the joint random variable (X, Y). Find the Least squares regression line and graph it with the support
5) Let X and Y have joint probability density function Graph the support of the joint random variable (X, Y). Find the Least squares regression line and graph it with the support
3. A regression analysis of a data set yielded the Least Squares regression line: y = 15.8 − 0.7 x. (a) What would be the estimated mean of Y when X = 9? (b) A student said: “ If we plug x = 10 in the equation of the regression line, then we get an estimate for the value of Y.” What is wrong with this statement? (c) By how much, and in what direction, would you expect Y to...
