Answer these questions
The image presents an exercise involving the prediction of an earned run average (ERA) based on a given dataset. The dataset contains the number of wins and the corresponding ERAs for eight baseball pitchers. 

The exercise is structured into three parts:

1. **Predict the ERA for 5 wins.**
   - (a) Options:
     - A: Predict ERA using the equation and round to two decimal places.
     - B: It's not meaningful because 5 is not within the range of the original data.
     - C: It's not meaningful because 5 is outside the range of the original data.

2. **Predict the ERA for 10 wins.**
   - (b) Options:
     - A: Predict ERA using the equation and round to two decimal places.
     - B: It's not meaningful because 10 is inside the range of the original data.
     - C: It's not meaningful because 10 is not an x-value in the original data.

3. **Predict the ERA for 19 wins.**
   - (c) Options:
     - A: Predict ERA using the equation and round to two decimal places.
     - B: It's not meaningful because 19 is inside the range of the original data.
     - C: It's not meaningful because 19 is not an x-value in the original data.

**Data Table:**

The data table provided lists the following values:

- Wins (x): 20, 18, 16, 14, 12, 11, 9
- Earned Run Average (y): 2.64, 3.32, 3.81, 3.92, 4.39, 3.86, 5.02

The task involves using this information to determine the meaningfulness of ERA predictions for specified win counts, considering the range and values of the original dataset.

**Linear Regression Analysis of Baseball Data**

The accompanying data are the number of wins and the earned run averages (ERA) (meaning the number of earned runs allowed per nine innings pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Use the regression equation to predict the value of \( y \) for each of the given \( x \)-values, if meaningful. If the \( x \)-value is not meaningful to predict the value of \( y \), explain why not.

1. **Predict the ERA for 5 wins, if it is meaningful.** Select the correct choice below and, if necessary, fill in the answer box within your choice.
   
   - A. \( \hat{y} = \) [ ] (Round to two decimal places as needed.)
   - B. It is not meaningful to predict this value of \( y \) because \( x = 5 \) is well outside the range of the original data.
   - C. It is not meaningful to predict this value of \( y \) because \( x = 5 \) is not an \( x \)-value in the original data.

2. **Predict the ERA for 10 wins, if it is meaningful.** Select the correct choice below and, if necessary, fill in the answer box within your choice.
   
   - A. \( \hat{y} = \) [ ] (Round to two decimal places as needed.)
   - B. It is not meaningful to predict this value of \( y \) because \( x = 10 \) is inside the range of the original data.
   - C. It is not meaningful to predict this value of \( y \) because \( x = 10 \) is not an \( x \)-value in the original data.

3. **Predict the ERA for 19 wins, if it is meaningful.** Select the correct choice below and, if necessary, fill in the answer box within your choice.
   
   - A. \( \hat{y} = \) [ ] (Round to two decimal places as needed.)
   - B. It is not meaningful to predict this value of \( y \) because \( x = 19 \) is well outside the range of the original data
