The number of goalsscored by each team appears in the home_score and away_score columns, respectively.Exercise 1 (1 point): Write an SQL query find the ten (10) teams that have the highest average away-scores since the year 2000. Your query should satisfy thefollowing criteria. It should return two columns:. team: The name of the teamave_goals: The team’s average number of goals in “away” games. An “away game” is one in which the team’s name appars in away_team and thegame takes place at a “non-neutral site” (neutral value equals FALSE).It should only include teams that have played at least 30 away matches. It should round the average goals value (ave_goals) to three decimal places.It should only return the top 10 teams in descending order by average away-goals.. It should only consider games played since 2000 (including the year 2000).Store your query string as the variable, query_top10_away, below. The test cell will run this query string against the input dataframe, df, defined above andreturn the result in a dataframe named offensive_teams. (See the test cell.)Note. The following exercises have hidden test cases and you’ll be awarded full points for passing both the exposed and hidden test cases.In [5]: query_top10_away =SELECT away_team, ROUND ( avg (away_score) , 3)FROM dataWHERE neutral is false and strftime( ‘ $H’, date) ; >= 2000GROUP BY away_team HAVING count ( *) >= 30ORDER BY ROUND ( avg ( away_score) , 3)DESC LIMIT 10;
