In constructing a confidence interval estimate for the difference between two population proportions,we pool the population proportions when the populations are normally distributed.

After 10½ years of contributions of $2,000 at the end of every six months to an RRSP, the accumulated amount stood at $65,727.82. What semi-annually compounded nominal rate and effective annual rate of return were earned by the funds in the RRSP?

Convert the annual rate to a monthly rate. Then, compute the simple interest on a monthly basis. Round answers to the nearest cent.
