You can put this solution on YOUR website! .
Use the recommended empirical rule (as presented in the book).
By the way, I don't know which book is recommended and referred to in this problem,
as well as no one of the tutors of this forum knows it.
Also, it is not a way to formulate a Math problem as you do in your post.
Therefore, you obtain this response in the form as it is.
