We are studying mutual bond funds for the purpose of investing in several funds. For this particular study, we want to focus on the
assets of a fund and its 5-year performance. The question is: Can the 5-year rate of return be estimated based on the assets of the
fund? Nine mutual funds were selected at random, and their assets and rates of return are as follows:
Assets
