1. **Stating the problem:** We have data set A with 15 values: 5 values of 22, 4 values of 23, 3 values of 24, 2 values of 25, and 1 value of 26. Data set B is created by adding 46 to each value in data set A. We need to compare the medians and ranges of data sets A and B.
2. **Recall definitions:**
- The **median** is the middle value when data is ordered.
- The **range** is the difference between the maximum and minimum values.
3. **Find the median of data set A:**
- Since there are 15 values, the median is the 8th value when ordered.
- Counting from smallest to largest:
- 5 values of 22 (positions 1 to 5)
- 4 values of 23 (positions 6 to 9)
- The 8th value is within the 23s, so median of A is $23$.
4. **Find the range of data set A:**
- Minimum value is $22$.
- Maximum value is $26$.
- Range of A is $$26 - 22 = 4$$.
5. **Create data set B by adding 46 to each value:**
- Minimum value of B is $22 + 46 = 68$.
- Maximum value of B is $26 + 46 = 72$.
6. **Find the median of data set B:**
- Adding a constant to all values shifts the median by that constant.
- Median of B is $$23 + 46 = 69$$.
7. **Find the range of data set B:**
- Range of B is $$72 - 68 = 4$$.
8. **Compare medians and ranges:**
- Median of B ($69$) is greater than median of A ($23$).
- Range of B ($4$) is equal to range of A ($4$).
**Final answer:** a. the median of data set B is greater than the median of data set A, and the range of data set B is equal to the range of data set A
