Question

a delivery company did a survey to find more about the parcels they were delivering Complete the table of cumulative frequencies(c.f) and plot the points

Answer 1

Explanation:

Mass (m kg) frequency mass (m kg) c.f.

0 < m ≤ 0.1 4 m ≤ 0.1 4

0.1 < m ≤ 0.2 6 m ≤ 0.2 10

0.2 < m ≤ 0.5 58 m ≤ 0.5 68

0.5 < m ≤ 0.8 28 m ≤ 0.8 96

0.8 < m ≤ 1.0 4 m ≤ 1.0 100

Total number of parcels surveyed = cumulative frequency = 100
