Stuck on this, confused on how to find the formula. Please help

STEP: 2 of 2 The measure of standard error can also be applied to the parameter estimates resulting from linear regressions. For example, consider the following linear regression equation that describes the relationship between education and wage: WAGE; = Bo + B EDUC;+ &; where WAGE, is the hourly wage of person i (i.e., any specific person) and EDUC, is the number of years of education for that same person. The residual &; encompasses other factors that influence wage, and is assumed to be uncorrelated with education and have a mean of zero. Suppose that after collecting a cross-sectional data set, you run an OLS regression to obtain the following parameter estimates: WAGE; = -11.5 + 3.1 EDUC, If the standard error of the estimate of B1 is 1.04, then the true value of B1 lies between A and . As the number of observations in a data set grows, you would expect this range to in size
