Please create a SQL query: The query should display JobTitle and the average VacationHours, grouped by JobTitle, and sorted so that the highest average VacationHours value appears at the top.

An example of the SQL code for a similar query:

SELECT CountryRegionCode, FORMAT(SUM(SalesYTD),'C')AsTotalSalesYTD

FROM Sales.SalesTerritory

GROUP BY CountryRegionCode

ORDER BY SUM(SalesYTD) DESC
