I had put7% but that was incorrect.

The ogive 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 ogive, 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%.) Estimate the median. The median is 5%. (Round to the nearest whole number as needed.) Estimate the quartiles. The lower quartile is 3% (Round to the nearest whole number as needed.) The upper quartile is 10% (Round to the nearest whole number as needed.) Estimate the range and the IQR. The range is % (Round to the nearest whole number as needed.)

Solution

From the figure, we see that

RANGE = max - min = 17 - (-7)= 24% [ANSWER]

******************

IQR = Q3 - Q1 = 8% - 3% = 5% [ANSWER]
