2. InnerSloth continue to update their popular video game Among Us.² Scraping their server logs, we have the sample data below. For the number of players, the sample statistics include a mean of about 7.7778 players and a standard deviation of about 1.3017 players. For the game times, the sample statistics include a mean of about 407.5556 seconds and a standard deviation of about 68.4235 seconds. The correlation between the number of players and the game time is about 0.9012. (a) Build a linear regression model for the sample data. (b) Use the model to predict the length of a game that has nine players. Players Time 6 353 6 312 315 420 464 7 8 8 8 8 9 10 404 423 482 495

Solve question 2.

1. In the video game Final Fantasy VII: Remake, one protagonist is named Tifa Lockhart, and the damage she dishes out with her punches are normally distributed with a mean of 19 and a standard deviation of 7. During a battle, if Tifa delivered 97 punches, what is the probability that the average punch damage was between 18 and 21. 2.
