I have a regression x(t) = at+b, number of trials, and R2 of the regression. How do I find the value and 95% confidence interval for the value of V = x/t?
Thank you

Just in case someone is interested, here is the solution:
V = a +/- da
da = t(percentile, N-2) sigma
sigma = a* sqrt( (1/R^2 - 1)/(N-2))
