Maple Ledger binned 40 invoice-processing times: 0–5 min: 8 · 5–10: 14 · 10–15: 11 · 15–20: 5 · 20–25: 2. Fill the two missing cells of the table: the relative frequency of the 5–10 bin, and the cumulative relative frequency through the 10–15 bin. Tolerance: exact to three decimals.

Answer

Relative frequency, 5–10 min → 0.35 · Cumulative relative frequency through 10–15 min → 0.825

Cells - Relative frequency, 5–10 min · ±0 - Cumulative relative frequency through 10–15 min · ±0 Relative frequency = f/n = 14/40 = 0.350. Cumulative through 10–15 = 0.200 + 0.350 + 0.275 = 0.825 — the running sum of the relative-frequency column, i.e. (8 + 14 + 11)/40 = 33/40.
