The table below gives the deviations of a hypothetical portfolio's annual total returns (gross of
fees) from its benchmark's annual returns, for a 12-year period ending in 2003.

1993...................................... 1.62
1994...................................... 2.48
1995...................................... ˆ’2.59

A. Calculate the frequency, cumulative frequency, relative frequency, and cumulative relative frequency for the portfolio's deviations from benchmark return, given the set of intervals in the table that follows.

B. Construct a histogram using the data.
C. Identify the modal interval of the grouped data.
