1.An experiment was performed on a certain metal to determine if the strength is a function of heating time (hours). Results based on 20 metal sheets are given below. Use the simple linear regression model. ∑X = 40∑X2 = 200∑Y = 70∑Y2 = 545∑XY = 320 Find the estimated y intercept and slope and write the equation of the least squares regression line. Estimate Y when X is […]
