An experiment was performed on a certain metal to determine if the strength is a function of heating time (hours). Results based on 25 metal sheets are given below. Use the simple linear regression model.
X= 50
X2= 200
Y= 75
Y2= 1600
XY= 400
Find the estimated y intercept and slope. Write the equation of the least squares regression line and explain the coefficients.
