Answer 1

(16)

Given:

Complaint	Frequency
Furniture scratched	5
Missing items	20
Broken glass	7
late arrival for pick up	30

(a)

Total frequency = 30 + 20 + 7 + 5 = 62

Complaint	Frequency	Percent frequency (%)	Cumulative percent frequency (%)
Late arrival for pick up	30	30/62*100 = 48.39	48.39
Missing items	20	20/62*100 = 32.26	48.39 + 32.26 = 80.65
Broken glass	7	7/62*100 = 11.29	80.65 + 11.29 = 91.94
Furniture scratched	5	5/62*100 = 8.06	91.94 + 8.06 = 100.00

Hope the answer will help. Please like the answer if you find it helpful. Thank you.
