標題[問題] 統計檢定

我想請問這題應該用何種檢定
A chemical process has produced on the average,800 tons of chemical per day.
The daily yields for the past week are 785,805,790,793,802 tons.
Do these data indicate that the average yield is less than 800 tons,
and hence that something is wrong with the process?
Test the 5% level of significance.
謝謝^^
