21, 19, 20, 18, 18, 17, 15, 10, 12, 13, 18, 18, 20, 19
Yuan uses the template below to create a histogram with bins as shown:
10-13
14-17
18-21
Which bar will be the highest? Identify the range for the correct bar.

Answer 1

To determine which bar in the histogram will be the highest, we need to count how many of Yuan's recorded low temperatures fall within each defined bin.

The bins are:
- 10-13
- 14-17
- 18-21

Now, let's analyze the data points Yuan recorded:

**Data Points:**
21, 19, 20, 18, 18, 17, 15, 10, 12, 13, 18, 18, 20, 19

**Counting temperatures by bin:**
1. **10-13**:
- The temperatures in this range are: 10, 12, 13
- Count: 3

2. **14-17**:
- The temperatures in this range are: 15, 17
- Count: 2

3. **18-21**:
- The temperatures in this range are: 21, 19, 20, 18, 18, 18, 18, 20, 19
- Count: 8

**Summary of counts:**
- 10-13: 3
- 14-17: 2
- 18-21: 8

**Conclusion:**
The highest bar will be for the range **18-21**, with a count of 8 temperatures.
