WILL MEDAL! I have a summary data from a recent stats class taught but much of the actual data had been lost. On the seventh exam the mean score was 83 and the standard deviation for the population of students in the class was 8.What are likely values for the minimum and maximum score on that exam? Thank you so much!

No this is a question i was given and am having a bit of trouble

OpenStudy (tomfoolery1):

This helps but i am still confused as to how to apply it

OpenStudy (mathmale):

In a situation like this one, 95% of scores will lie within 2 standard deviations of the mean. What is the std. dev. in this case? What scores correspond to 1 and 2 std. devs. from the mean?
