The give shown below is the distribution of monthly returns

The give shown below is the distribution of monthly returns for a group of aggressive (or high growth) mutual funds over a period of 25 years from 1975 to 1999. (Recall that an give, or cumulative relative frequency graph, shows the percent of cases at or below a certain value. Thus: this graph always begins at 0% and ends at 100%.)

Solution

the upper quartile is 10% because it is that value under which 75% frequency exists. so from the graph it is found to be 10% monthly return [rounded to the nearest whole number.] here X=75 cuts the ogive at that point , at which Y=10 cuts the ogive. hence the answer
