The table below shows the amount, in inches, of annual rainfall in a sample of 52 towns. Complete the last column, the cumulative relative frequency column, of the table above.  (Give answers as decimals rounded to 2 decimal places.) Hint:  To find the cumulative relative frequencies, add all the previous relative frequencies to the relative frequency for the current row. For the second row:  cumulative relative frequency = 0.15 + 0.12 = 0.27 Rainfall (Inches) Frequency Relative Frequency Cumulative Relative Frequency 2.95–4.97 8 0.15 0.15 4.97–6.99 6 0.12 0.27 6.99–9.01 16 0.31 9.01–11.03 10 0.19 11.03–13.05 9 0.17 13.05–15.07 3 0.06 Total = 52 Total = 1.00 What fraction of the 52 towns surveyed get between 11.03 and 13.05 inches of rainfall each year?  (Give answer in the “a/b” fraction form.)
