I need help finding the y intercept and slope. writing the equation of the least squares regression line and explaining the coefficients. Estiamte Y and X is equal to 4 hours.I also need assistance determining the standard error, mean square error, and the coefficient of determination and coefficient of corrleation. Test the signifcance of the slope.

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
