For a 68.26% confidence, z = 1.0.
Standard deviation (s) = 30 minutes
The sample size needed to assure that the sample mean does not differ from the true mean by more than 5 minutes is given by:
The sample size needed is 36.
The distance: use absolute value
Between x and 8: x-8

The distance between x and 8 is no more than 4
| x-8 | ≤ 4
