Solution

For this case we can do the following:

(a) What percentage of the shoppers do not have computer access at home?

[tex]p=\frac{25+125}{250}=\frac{150}{250}=0.6[/tex]

And if we convert to % we got 60%

(b) What percentage of the shoppers have an e-mail account?

[tex]p=\frac{75+25}{250}=\frac{100}{250}=0.4[/tex]

And if we convert to % we got 40%
