then, we get
that is, P_38 corresponds to 41 miles driven.
In the second case, by substituting x=60 in our formula, we get
which gives
that is, P_60 corresponds to 56 miles driven.
Then, the answers are:
This means that approximately 38% of the data lie below 41, when the data are ranked.
This means that approximately 60% of the data lie below 56, when the data are ranked.
