Analysts have been studying the relationship between the high points of the Dow Jones for each year since 2009. A computer regression analysis of the data is given below:
Dependent variable is: Dow Jones Industrial Average (DJI)
$R^2 = 93.33\%$
$s= 1116.14$, with $6-2= 4$ D.O.F.
Assuming all of the conditions have been satisfied, which of the following gives a $90\%$ confidence interval for the slope of the regression line?
