Consider the Sample Regression Function $\hat { Y }$ _i = $\hat{\beta} _ { 0 }$

Essay

Consider the sample regression function $\hat { Y }$ _i = $\hat{\beta} _ { 0 }$ + $\hat{\beta} _ { 1 }$ X_i. The table below lists estimates for the slope ( $\hat{\beta }_ { 1 }$ )and the variance of the slope estimator ( $\hat { \sigma } ^ { 2 } { \hat { \beta } 1 }$ ). In each case calculate the p-value for the null hypothesis of ?₁ = 0 and a two-tailed alternative hypothesis. Indicate in which case you would reject the null hypothesis at the 5% significance level. $\begin{array}{|c|c|c|c|c|} \hline \hat{\beta } _1& -1.76&0.0025&2.85&-0.00014\\\hline \hat{\sigma}^2\hat{\beta}_1&0.37&0.000003&117.5&0.0000013\\\hline\end{array}$
