**Investigating the Relationship Between Batting Average and Games Won in Softball Teams**Is the number of games won by a softball team in a season related to the team batting average? The table below displays the batting average (in thousandths) and the number of games won for 8 different teams.| Team | Batting Average | Games Won ||------|-----------------|-----------|| 0 | 313 | 41 || 1 | 297 | 36 || 2 | 316 | 48 || 3 | 303 | 31 || 4 | 281 | 46 || 5 | 259 | 45 || 6 | 273 | 39 || 7 | 318 | 43 |**Analysis Tasks:**Using games won as the explanatory variable $ x $, perform the following analyses:a. Find the correlation coefficient $ r $.b. Determine the equation of the least squares line $ \hat{y} $. The data aims to explore any potential correlation and linear relationship between a team's batting average and the number of games they win, offering insights into factors that might influence team success.

It is required to obtain the correlation coefficient, r, and the equation of the least squares…
