To solve the questions, we need to analyze the data provided in the table.
The survey results can be summarized as follows:
- Number of shoppers with a computer at home and an e-mail account: 30
- Number of shoppers with a computer at home and no e-mail account: 6
- Number of shoppers without a computer at home and an e-mail account: 4
- Number of shoppers without a computer at home and no e-mail account: 60
Total breakdown:
-
Total number of shoppers with a computer at home:
- With e-mail account: 30
- Without e-mail account: 6
- Total with computer access = 30 + 6 = 36
-
Total number of shoppers without a computer at home:
- With e-mail account: 4
- Without e-mail account: 60
- Total without computer access = 4 + 60 = 64
Total shoppers surveyed:
- \( 36 + 64 = 100 \) (as mentioned)
(a) What percentage of the shoppers have an e-mail account?
Total number of shoppers with an e-mail account:
- With computer access: 30
- Without computer access: 4
- Total with e-mail accounts = 30 + 4 = 34
Now to find the percentage: \[ \text{Percentage with e-mail account} = \left(\frac{\text{Total with e-mail accounts}}{\text{Total shoppers}} \right) \times 100 \] \[ = \left(\frac{34}{100}\right) \times 100 = 34% \]
(b) What percentage of the shoppers do not have computer access at home?
Total number of shoppers without computer access:
- Total without computer access = 64 (as calculated above)
Now to find the percentage: \[ \text{Percentage without computer access} = \left(\frac{\text{Total without computer access}}{\text{Total shoppers}} \right) \times 100 \] \[ = \left(\frac{64}{100}\right) \times 100 = 64% \]
Final Answers:
(a) 34%
(b) 64%
