Answer 1

Given,

Type of Complaint	Frequency
Too expensive	174
Unreliable/Frequently stops working	242
Page loading too slow	111
Download/Upload speed too slow	98
Extra data usage charges	67
Poor tech support	103
Long customer service wait times	59
Incorrect billing	46
Long wait for installation	75
Total	975

Total number of complaints = Sum of frequency of all complaints = 174+242+111+98+67+103+59+46+75=975

Percent of the complaints due to the category Unreliable/Frequently stops working

= (Frequency of Unreliable/Frequently stops working / Total number of complaints) * 100

= (242/975)*100 = 0.2482*100 = 24.82%

Percent of the complaints due to the category Unreliable/Frequently stops working = 24.82%
