Transcribed Image Text:**Educational Transcription: Linear Correlation Coefficient**
**Data Set:**
- \( x \): 10, 8, 9, 11, 14, 6, 4, 12, 7, 5
- \( y \): 9.13, 8.13, 8.75, 8.76, 9.26, 8.09, 6.13, 3.11, 9.13, 7.26, 4.74
**Task:**
Use the given data set to complete parts (a) through (c) below. (Use \(\alpha = 0.05\)).
**Graphs:**
Four scatter plots (labeled A, B, C, D) are provided, each depicting a different correlation relationship between variables \( x \) and \( y \).
**b. Linear Correlation Coefficient:**
- Find the linear correlation coefficient, \( r \), then determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables.
**Note:**
The linear correlation coefficient is \( r = \underline{\phantom{000}} \). (Round to three decimal places as needed).
**Instructions:**
Click "here" to view a table of critical values for the correlation coefficient.
**Graphs Explanation:**
- **Graph A:** Shows a positive linear trend.
- **Graph B:** Displays a negative linear trend.
- **Graph C:** Suggests a stronger positive linear relationship than A.
- **Graph D:** Exhibits a curved trend indicating a possible non-linear relationship.
