**Bivariate Data Analysis**The following table presents bivariate data for the quantitative variables \( x \) and \( y \). A scatter plot of this data is displayed next to the table, illustrating the relationship between the two variables.**Data Table:**| \( x \) | \( y \) ||--------|--------|| 7.5 | 8.8 || 2.9 | 1.8 || 3.4 | 3.4 || 5.7 | 4.7 || 3.2 | 2.9 || 4.0 | 1.7 || 4.4 | 3.5 || 5.2 | 3.6 || 6.8 | 6.5 || 8.5 | 9.5 || 4.5 | 4.4 || 5.8 | 7.3 || 6.7 | 6.9 || 10.6 | 8.8 || 7.5 | 7.6 || 8.1 | 9.6 || 5.6 | 4.4 || 8.7 | 9.8 || 6.4 | 5.2 |**Scatter Plot Explanation:**- The scatter plot is a graphical representation of the data with \( x \)-axis representing the variable \( x \) and the \( y \)-axis representing the variable \( y \).- Each point on the plot corresponds to a pair of values \( (x, y) \) from the table.- Observing the scatter plot, there appears to be a positive correlation between \( x \) and \( y \), meaning as \( x \) increases, \( y \) tends to increase as well.- To better understand this relationship, one can sketch an approximation of the least-squares regression line, which minimizes the distance between the data points and the line itself.You are encouraged to draw the least-squares regression line on the scatter plot to visually assess the strength and nature of the relationship between these variables.

The data shows the quantitative variables x and y. The scatter plot is given.
