Question
### Construct and Understand Frequency Tables for a Set of Data with Technology - Excel

#### Question

Sheri writes down the amount of time in minutes that it takes for her to commute to work each day for 20 consecutive days. The results are given below.

**Commute Times (in minutes):**

|   |   |   |   |   |
|---|---|---|---|---|
| 30 | 29 | 28 | 32 |   |
| 33 | 28 | 35 | 33 | 29 |
| 30 | 34 | 40 | 30 | 32 |
| 31 |   | 29 | 28 | 33 |
|   |   |   | 30 |   |


**Instructions:**

Use Excel to create a frequency table for the data. What is the longest commute time with a frequency greater than 1?

**Provide your answer below:**

\[ \text{Input Box} \]
[end of explanation text for input box]

[Options for interface]

- \[ Help \]
- \[ Copy to Clipboard \]
- \[ Download CSV \]

### Explanation for Creating a Frequency Table in Excel:

1. **Input Data:**
   - Enter the commute times into a single column in an Excel spreadsheet.

2. **Creating the Frequency Table:**
   - Select the range of data entered.
   - Use the function `=FREQUENCY(data_array, bins_array)` to calculate the frequency.
   - Create bins at even intervals (or use unique values) that cover the range of commute times in your data.

3. **Identify the Longest Commute Time with Frequency Greater Than 1:**
   - Review the frequency table.
   - Note the commute times and their corresponding frequencies.
   - Identify the maximum commute time that has a frequency greater than 1.

This exercise will help in understanding how to organize and summarize data efficiently using Excel's tools.
