It's a website that's pretty easy to use and answers math problems
The mean is given as 78.3
You want all numbers that are within 1 standard deviation (which is also given as 10.3).
So the smallest possible number is:
78.3 - 10.3 = 68
And the largest possible number is:
78.3 + 10.3 = 88.6
Answer:
Any death rates between 68 and 88.6 would be within 1 s.d. of the mean.
