The n= 44 , mean=104.13636, std.dev= 6.2490, median= 104 ,
range= 30
Based on the relationship between median and mode and the shape
of the histogram, does it appear that the distribution is
approximately bell shaped? (i.e. does the Empirical Rule
apply”?)
What approximate percent does the empirical rule say should be
within one
