Suppose the simple linear regression model, Y; = Bo + B1 x; + E;, is used to explain the relationship between x and y. A random sample of n = 10 values for the explanatory variable (x) was selected and the corresponding values of the response variable (y) were observed. The summary statistics were: Σο-8, Συ- 10, Σ-9.5, Σ-7.4,Συ?- 20
