A number of people were asked how many days they would wait to seek medical treatment if they were suffering pain that interfered with their ability to work. The results are presented in the following table.

Number of Days	Frequency
0	27
1	392
2	158
3	272
4	19
5	10

Consider this collection of people to be a population. Let X be the number of days for a person sampled at random from this population. Compute the mean of X.
