Question 1036043
The mean is 105.8 and the sd of the sample (I think this is a sample) is 14.3
Between 1 sd of the mean would include (91.5,120.1) or (92,120). That is 23/31 scores.
If the second part is 2 sd s of the mean (not written as such), it would be the interval (77.2,132.4) or (78,132).  That would be 29/31 scores.
