You are testing the ability of 200 students to solve two types of games. The corresponding dataset is namedgames.txt. The students are tested with a video game (column "video") and a board game (column "puzzle"). The values represent the scores. Provide R code for answer.

- Generate a scatter plot to show the relationship between the video score and the puzzle score of the students. Add the linear regression on the graph. Annotate the labels of the graph and include the PDF in your report.

- Conduct the linear regression, report the intercept and the slope and interpret the results.

- Conduct a correlation test; report the parameters of the correlation (coefficient and p-value) and conclude.
