Reference no: EM132848192

In an article about inflation, various investments were examined.

The investments included stocks, bonds, and real estate. Suppose that a random sample of 250 rates of return (in percentage) on real estate investments was computed and recorded. Assuming that the standard deviation of all rates of return on real estate investments in the market is 3.25 percent, estimate a confidence interval for the mean rate of return on all real estate investments with 99% confidence, 95% and 90%. Interpret the estimates.
