Question: What percentage does the shipment of products by Speedy Express to Sweden make up to the shipping company's total?
SQL: SELECT CAST(COUNT(CASE WHEN T1.ShipCountry = 'Sweden' THEN 1 ELSE NULL END) AS REAL) * 100 / COUNT(T1.OrderID) FROM Orders AS T1 INNER JOIN Shippers AS T2 ON T1.ShipVia = T2.ShipperID WHERE T2.CompanyName = 'Speedy Express'
