Sql: Explore and analyze the students data to see how the study reached its conclusions and gain a better understanding of it$.$ Specifically, you'll explore and analyze how the length of stay $($stay$)$ impacts the mental health of the international students present in the study.

Return a table with nine observations and five columns summarizing data for the international students: stay, count$\_$int, average$\_$phq$,$ average$\_$scs$,$ and average$\_$as$,$ in that order. The average columns should contain the average of the todep, tosc, and toas columns for each length of stay, rounded to two decimal places. The count$\_$int column should be the number of international students for each length of stay. Sort the results by the length of stay in descending order.

Note: Creating new cells in workspace will rename the DataFrame. Make sure that your final solution uses the name df$.$
