Regression estimation

Suppose we want to estimate the yield in tomatoes for a plot. Our outcome is the number (Y) of tomatoes in the plot. Early in the season, a worker counted all the tomatoes (X) ripening (green) on each plant. We know there are 1000 plants and to = 25000 green tomatoes counted. Suppose also that we find in our sample of n=100 plants the average number of green tomatoes counted earlier was XS = 20. If the intercept and slope for the regression of ripe tomatoes on green tomatoes are Bo = 4, B, = 0.9 and the residual sum of squares is _ = 10000 , then the estimated standard error of ty, reg Type your numeric answer and submit
