7. consider the data below

4,4,6,7,7,8,8,8,9,9,9,9,9,10,10,10,11,11,12
a) conduct a histogram with intervals of two
b) if a value of 20 is added to the data set, how will it affect the mean?
c) if a value of 20 is added to the data set, how will it affect the median?
d) if a value of 20 is added to the data set, how will it affect the measure of variability?
e) if you add a value of 30, what distribution shape would the data have?
f) if you add a value of 50 to the data would the mean be a good measure of center?
