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 [c3] 9.01–11.03 10 0.19 [c4] 11.03–13.05 9 0.17 [c5] 13.05–15.07 3 0.06 [c6] 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.) [x]
