Suppose the simple linear regression model, Y; = Bo + B1 xi + 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 esponse variable (y) were observed. The summary statistics were: E¤; = 8, Ey: = 10, E:Y; = 9.5, Ea = 7.4, Ey? = 20
