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) ? %

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.
