If $\hat { \beta } _ { 1 } = - 1.0 , \sum x _ { i } = 10 , \sum y _ { i } = 20 , \text { and } n = 15$

question 70

Short Answer

If $\hat { \beta } _ { 1 } = - 1.0 , \sum x _ { i } = 10 , \sum y _ { i } = 20 , \text { and } n = 15$ then the least squares estimate of the intercept $\beta _ { 0 }$ of the true regression line $y = \beta _ { 0 } + \beta _ { 1 } x \text { is } \hat { \beta } _ { 0 }$ = __________.
