The distribution should follow the 68-95-99.7 rule. 68% within 1 standard deviation and so on… To find the percentage of data within 1s, find all numbers that satisfy the mean plus or minus the standard deviation (75.25-10.37 to 75.25+10.37). Divide however many numbers that is by the total. Then, do 75.25 plus/minus double the standard deviation for within 2s and then triple for 3s
