Mutual funds are classified as load or no-load funds. Loadfunds require an investor to pay an initial fee based on apercentage of the amount invested in the fund. the no-load funds donot require this initial fee. some financial advisors argue thatthe load mutual funds may be worth the extra fee because thesefunds provide a higher mean rate of return than the no-load mutualfunds. A sample of 30 load mutual funds and a sample of 30 no-loadmutual funds were selected. data were collected on the annualreturn for the funds over a 5 year period. The data are containedin the data set mutual. The data for the first five load and firstfive no-load mutual funds are as follows.
