(a) Create a scatter diagram for the data.

(c) Approximate the relationship between \(x\) and \(y\) by drawing a straight line.

Answer :

Final answer:

A scatter diagram is used to visualize the relationship between two variables, while linear regression can approximate the relationship using a straight line.

Explanation:

A scatter diagram is a graph that plots pairs of numerical data, with one variable on the x-axis and the other on the y-axis. It helps visualize the relationship between the two variables. To approximate the relationship between x and y by drawing a straight line, we can use linear regression. Linear regression finds the best-fitting line through the data points, minimizing the distance between the points and the line.
