I need help calculating the correlation coeddicient r indicating the relationship between X and Y. I need to include the necessary deviation scores and sums of squares. With that, I need to conduct a hypothesis test whether the correlation between X and Y is significant. Provide the degrees of freedom and the cut-off value, assuming a two-tailed test with alpha = 0.05.  And then creating a scatterplot associated with the data.

I need help calculating the correlation coeddicient r indicating the relationship between X and Y. I need to include the necessary deviation scores and sums of squares.

With that, I need to conduct a hypothesis test whether the correlation between X and Y is significant. Provide the degrees of freedom and the cut-off value, assuming a two-tailed test with alpha = 0.05. 

And then creating a scatterplot associated with the data.

### Data Table The table below represents two sets of data points labeled as DATA X and DATA Y. Each row corresponds to a pair of values, where the first column (DATA X) indicates the independent variable and the second column (DATA Y) represents the dependent variable. | DATA X | DATA Y | |--------|--------| | 2 | 60 | | 19 | 56 | | 20 | 50 | | 42 | 50 | | 42 | 45 | | 59 | 39 | | 60 | 36 | | 61 | 33 | | 66 | 27 | | 68 | 27 | | 89 | 23 | | 91 | 19 | | 94 | 18 | | 96 | 15 | | 98 | 7 | ### Explanation of the Data 1. **Independent Variable (DATA X)**: - This column represents a set of values that are being manipulated or changed in the experiment or observation. - It includes a range of values from 2 to 98. 2. **Dependent Variable (DATA Y)**: - This column represents the response or outcome that is observed as a result of changes in the independent variable. - It includes a range of values from 7 to 60. ### Potential Applications Understanding the relationship between DATA X and DATA Y can be crucial in fields such as statistics, scientific research, and data analysis. By analyzing these data points, one might be able to identify trends, correlations, or patterns that can lead to valuable insights and conclusions. For example, plotting these data points on a graph could visually demonstrate how changes in DATA X affect DATA Y.
