Question

In a survey, 200 shoppers were asked whether they have access to a computer at home and if they have a personal e-mail account. Their responses are summarized in the following table.

E-Mail account No e-mail account
Computer access at home
No computer access at home

(a) What percentage of the shoppers have an e-mail account?
(b) What percentage of the shoppers have computer access at home?

(a) ? %
(b) ? %

Answer 1

To answer the questions, we need to have the summarized data from the survey results. However, since you have not provided the specific numbers in the table, I will demonstrate how to calculate the percentages based on hypothetical numbers. You can then apply this method to your actual data.

### Hypothetical Data Example
Let’s say the summarized results are as follows:

| | E-Mail Account | No E-Mail Account | Total |
|-----------------------------|----------------|-------------------|-------|
| **Computer Access at Home** | 100 | 50 | 150 |
| **No Computer Access at Home** | 30 | 20 | 50 |
| **Total** | 130 | 70 | 200 |

### Calculations

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

To find the percentage of shoppers with an e-mail account:
1. Count the total number of shoppers with an e-mail account.
2. Divide this number by the total number of shoppers, then multiply by 100.

Using the hypothetical data:
- Total with E-Mail Account = 130
- Total Shoppers = 200

\[
\text{Percentage with E-Mail Account} = \left(\frac{130}{200}\right) \times 100 = 65\%
\]

#### (b) What percentage of the shoppers have computer access at home?

To find the percentage of shoppers with computer access at home:
1. Count the total number of shoppers with computer access at home.
2. Divide this number by the total number of shoppers, then multiply by 100.

Using the hypothetical data:
- Total with Computer Access at Home = 150
- Total Shoppers = 200

\[
\text{Percentage with Computer Access at Home} = \left(\frac{150}{200}\right) \times 100 = 75\%
\]

### Summary

For the hypothetical data:
- (a) 65%
- (b) 75%

You can replace the hypothetical numbers with the actual numbers from your survey dataset and perform the same calculations.
