Consider the following data set:

a. Show that this data set does not come from an approximately normal population.

b. Take the reciprocal of each value in the data set (the reciprocal of x is 1∕x). This is called a reciprocal transformation of the data. Show that the reciprocals may be considered to be a sample from an approximately normal population.
