Answer: SELECT PageName, SUM(TimeSpent) AS TotalTimeSpent, AVG(TimeSpent) AS AverageTimeSpent FROM WebsiteVisits WHERE Country = 'USA' GROUP BY PageName;
Option A is correct because it accurately filters the dataset for visitors from 'USA' using the WHERE clause, groups the results by page name, and calculates both the total time spent (SUM) and the average time spent (AVG) on each page. This approach provides a comprehensive view of page engagement, which is essential for content strategy optimization. Options B, C, and D either fail to provide both metrics, incorrectly use the HAVING clause without GROUP BY, or omit the GROUP BY clause entirely, leading to incomplete or incorrect results.

Choose the SQL query that best retrieves the total time spent on each page by visitors from 'USA', along with the page name, and also considers the average time spent to provide a comprehensive view of engagement. Select one option.
A
SELECT PageName, SUM(TimeSpent) AS TotalTimeSpent, AVG(TimeSpent) AS AverageTimeSpent FROM WebsiteVisits WHERE Country = 'USA' GROUP BY PageName;
B
