Answer:
a). 36%
b). 58%
Step-by-step explanation:
From the given table in the question,
Total number of the shoppers who were surveyed = 150
a). Number of shoppers who have an e-mail account = Shoppers who have email accounts and computer access at home + Shoppers who have email accounts but no computer access at home
= 44 + 10
= 54
Percentage of the shoppers having an e-mail account = [tex]\frac{54}{150}\times 100=36[/tex]%
b). Total number of shoppers who do not have computer access at home
= 10 + 77
= 87
Percentage of the shoppers having computer access at home = [tex]\frac{\text{Number of shoppers not having access at home}}{\text{Total shoppers surveyed}}\times 100[/tex]
= [tex]\frac{87}{150}\times 100[/tex]
= 58%
