(Help would be very appreciated)​

Answer 1

a) To determine the percentage of shoppers who have an e-mail account, we need to add up the number of shoppers who responded "Yes" to the e-mail question. From the table, we see that 58 shoppers have an e-mail account and computer access at home, and 110 shoppers have an e-mail account but no computer access at home. Therefore, the total number of shoppers with an e-mail account is:

58 + 110 = 168

To find the percentage, we divide this number by the total number of shoppers (200) and multiply by 100:

(168/200) x 100 = 84%

So, 84% of the shoppers have an e-mail account.

b) To determine the percentage of shoppers who have computer access at home, we need to add up the number of shoppers who responded "Yes" to the computer access question. From the table, we see that 58 shoppers have computer access at home and an e-mail account, and 14 shoppers do not have computer access at home but have an e-mail account. Therefore, the total number of shoppers with computer access at home is:

58 + 14 = 72

To find the percentage, we divide this number by the total number of shoppers (200) and multiply by 100:

(72/200) x 100 = 36%

So, 36% of the shoppers have computer access at home.
