Let's work through the questions in the image step by step.

### 1. Data provided:
- **Data a**: 20, 18, 15, 11, 12, 13, 14
- **Data b**: 30, 15, 16, 17, 18, 27, 14, 26

#### a. Find \(\bar{x}\) (Mean):
The mean is calculated by summing all the data points and dividing by the number of data points.

For **Data a**:
\[
\bar{x}_a = \frac{20 + 18 + 15 + 11 + 12 + 13 + 14}{7}
\]

For **Data b**:
\[
\bar{x}_b = \frac{30 + 15 + 16 + 17 + 18 + 27 + 14 + 26}{8}
\]

#### b. Find the Median (\(Me\)):
The median is the middle value when the data is arranged in order.

For **Data a**: Sort: 11, 12, 13, 14, 15, 18, 20. The median is the 4th value (middle value).

For **Data b**: Sort: 14, 15, 16, 17, 18, 26, 27, 30. Since there are 8 values (even), the median is the average of the 4th and 5th values.

### 2. Baby Weight Data:
Weights provided:
\[
15, 16, 21, 25, 35, 14, 13, 12, \dots, 35
\]
You are asked to:
a. Create a frequency distribution,
b. Find the mean (\(\bar{x}\)),
c. Find the median (\(Me\)).

Let me calculate everything step by step for the first part, and I'll show you the results for \(\bar{x}\) and \(Me\). I'll begin with calculations for problem 1.### Results for Problem 1:

- **Mean (\(\bar{x}\))**:
  - For **Data a**: \(\bar{x}_a = 14.71\)
  - For **Data b**: \(\bar{x}_b = 20.38\)

- **Median (Me)**:
  - For **Data a**: \(Me_a = 14\)
  - For **Data b**: \(Me_b = 17.5\)

Now, I will proceed with Problem 2 by creating the frequency distribution and calculating the mean and median for the baby weight data.It seems like I can’t do more advanced data analysis right now. Please try again later.

In the meantime, if you would like help in understanding the steps to solve the rest of the problem (such as frequency distribution, mean, and median for the baby weight data), I can guide you through the process manually. Let me know how you'd like to proceed!

Here are 5 relative questions to expand on this:

1. How do you calculate the frequency distribution for grouped data?
2. What is the importance of finding the mean in a dataset?
3. Why is the median used as a measure of central tendency?
4. What is the difference between mean and median, and when should you use each?
5. How does outlier data affect the mean and median?

**Tip:** When working with a large dataset, always sort the data first for easier identification of the median and calculation of the frequency distribution.
