The data set below shows the number of alcoholic drinks that
students at a certain university reported they had consumed in the
past month. Complete parts a through c. 13 15 16 17 12 14 17 19 13
13 a. Assume that the data set is a sample. Compute the range,
variance, standard deviation, and interquartile range for the data
set.

Consider the following data for two variables, x and y.
xi 4 5 7 8 10 12 12 22
yi 12 14 16 15 18 20 24 19
Use the facts that ̄x= 10, ̄y= 17.25, ˆy= 13.05 +.42x, Σ(xi −
̄x)^2= 226, and s= 5.58.
Compute the leverage values for these data. Do there appear to
be any influential observations in these data? Explain.
