    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.
