You Have Collected Data for the 50 U $\widehat{\Delta u r}$

question 56

Multiple Choice

You have collected data for the 50 U.S. states and estimated the following relationship between the change in the unemployment rate from the previous year ( $\widehat{\Delta u r}$ ) and the growth rate of the respective state real GDP (g_y) . The results are as follows $\widehat{\Delta u r}$ = 2.81 - 0.23 $\times$ g_y, R²= 0.36, SER = 0.78 (0.12) (0.04)
Assuming that the estimator has a normal distribution, the 95% confidence interval for the slope is approximately the interval
