Answer 2

a). 36%

b). 58%

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 =
`(54)/(150)* 100=36`%

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 =
`\frac{\text{Number of shoppers not having access at home}}{\text{Total shoppers surveyed}}* 100`

=
`(87)/(150)* 100`

= 58%
