HELP!!! If it said that the variance was 8 days instead, would you do square root of 8 when putting it into the calculator?

For a, are we meant to use our calculators?  Do they still give out table booklets in exams. If so do I need to use x-mean/ standard dev for this to get  97-95/8 which is 0.25 and look that up.  ?  Very confusing.  Exams tom  .. Thanks,
