Let's analyze the table to answer the given questions.

The table shows data on cell phone ownership across three age groups (18-34, 35-54, and 55+), with information on the type of phone (iPhone, Android, or Other) for each group.

### (a) What proportion of iPhone owners were 55 or older?

- From the table, the total number of iPhone owners is **467**.
- The number of iPhone owners aged 55 or older is **127**.

The proportion of iPhone owners 55 or older is calculated as:
\[
\text{Proportion} = \frac{\text{Number of iPhone owners aged 55+}}{\text{Total iPhone owners}} = \frac{127}{467}
\]

Let me calculate this.

### (b) What percent of 18- to 34-year-olds owned Android phones?

- The total number of people aged 18-34 is **517**.
- The number of Android owners aged 18-34 is **214**.

The percentage of 18-34-year-olds who owned Android phones is:
\[
\text{Percentage} = \left(\frac{\text{Number of Android owners aged 18-34}}{\text{Total number of 18-34-year-olds}} \right) \times 100 = \left( \frac{214}{517} \right) \times 100
\]

Let me calculate both answers.### (a) The proportion of iPhone owners who were 55 or older is approximately **0.272** (or 27.2%).

### (b) The percentage of 18- to 34-year-olds who owned Android phones is approximately **41.39%**.

Would you like any further details or clarifications? Here are some additional related questions for practice:

1. What proportion of the total sample were iPhone owners?
2. What percent of people aged 55+ owned Android phones?
3. What proportion of 35-54-year-olds owned "Other" types of phones?
4. What is the most popular phone type among the 18-34 age group?
5. What percentage of the total sample owned non-smartphones ("Other")?

**Tip**: To convert a proportion to a percentage, simply multiply by 100!

What proportion of iPhone owners were 55 or older? What percent of 18- to 34-year-olds owned Android phones?

Analyze phone ownership across different age groups with a focus on calculating the proportion of iPhone users aged 55+ and the percentage of 18- to 34-year-olds who own Android phones. Includes detailed calculations and explanations for basic percentage and proportion problems.
