2162 were called by landline and 1177 were called by cell phone. What percentage of the survey subjects were called by cell phone?

To calculate the percentage of survey subjects who were called by cell phone, we use the following formula:

\[
\text{Percentage} = \left( \frac{\text{Number of people called by cell phone}}{\text{Total number of people called}} \right) \times 100
\]

The total number of people called is the sum of those called by landline and by cell phone:

\[
\text{Total number of people called} = 2162 + 1177 = 3339
\]

Now, calculate the percentage:

\[
\text{Percentage} = \left( \frac{1177}{3339} \right) \times 100 \approx 35.25\%
\]

So, approximately **35.25%** of the survey subjects were called by cell phone.

4. How does the ratio of landline to cell phone calls affect survey bias?
5. If the total number of people called was doubled, what would happen to the percentage?

**Tip:** When working with percentages, always ensure you calculate the total number first for accurate results.
