An experiment was performed on a certain metal to determine if the strength is a function of heating time (hours). Results based on 30 metal sheets are given below. Use the simple linear regression model.
X= 60
X2= 200
Y= 90
Y2= 550
XY= 316
Find the estimated y intercept and slope and write the equation of the least squares regression line.Estimate Y when X is equal to 3 hours. Alsodetermine the standard error, the Mean Square Error, the coefficient of determination and the coefficient of correlation and show their relation.
