Question 2

Question 2

Revolt · Accepted Answer

The team from the second league would be more likely to win because the teams in that league show more consistent performance and generally higher numbers of home runs and wins. In contrast, the data for the first league shows more variability and outliers. Therefore, the second league's consistency makes them a more predictable and stronger choice to win a game.

Question 3

Check all that you included in your answer.

Revolt · Accepted Answer

Teams in the second league seem more consistent; there are low and high outliers in the data for the first league.; A team in the league with the more consistent number of home runs and wins will probably be more likely to win.; Teams in the second league are more likely to get home runs and win, so a team in that league is more likely to win.

Question 4

What is the average rate of change of the trend line? Round to the nearest hundredth.

Revolt · Accepted Answer

0.39

Question 5

The equation of the trend line is y = 0.39x – 20.23✔ y = 0.39x + 20.23y = –0.39x – 20.23y = –0.39x + 20.23

Revolt · Accepted Answer

✔ y = 0.39x + 20.23

Question 6

What is the y-intercept of the trend line, to the nearest hundredth?

Revolt · Accepted Answer

-23.21

Question 7

The equation of the trend line is y = –0.15x + 23.21y = –0.15x – 23.21y = 0.15x + 23.21✔ y = 0.15x – 23.21

Revolt · Accepted Answer

✔ y = 0.15x – 23.21
