Answer:
a) 70%, 64%, 67%
Step-by-step explanation:
Total customers surveyed = 500
Number of men = 250
Number of women = 250
Number of men who rated the customer service excellent = 175
Number of women who rated the customer service excellent = 160
Total number of customers who rated the customer service excellent = [tex]175+160 =335[/tex]
Percentage of men who rated the customer service excellent
⇒ [tex]\frac{\textrm{Number of men who rated excelent}}{\textrm{Total number of men}}\times 100[/tex]
⇒ [tex]\frac{175}{250}\times 100[/tex]
⇒ 70%
Percentage of women who rated the customer service excellent
⇒ [tex]\frac{\textrm{Number of women who rated excelent}}{\textrm{Total number of men}}\times 100[/tex]
⇒ [tex]\frac{160}{250}\times 100[/tex]
⇒ 64%
Percentage of customers who rated the customer service excellent
