NOTE: the problem statement doesn't say whether it wants the "sample standard deviation" or the "population standard deviation", so I provide you with both, and you can choose which one the teacher wants.

range = 97 - 82 = 15
sample standard deviation = 6.51920240520264
sample variance = 42.5
population standard deviation = 5.8309518948453
population variance = 34
mode = 97

as for the table and histogram, you can do that yourself
