Question

An experiment was performed on a certain metal to determine if the strength is a function of heating time.Results based on 10 metal sheets are given below.Use the simple linear regression model.

\sum X

= 30

\sum X ^ { 2 }

= 104

\sum Y

= 40

\sum Y ^ { 2 }

= 178

\sum X Y

= 134
-Find the t statistic and test H₀:
