Question 235550: The apollo space craft program lasted from 1967 to 1972 and incl 13 missions. The missions lasted from as little as 7 hrs to as long as 301 hrs. The duration of each flight is listed below:
9-195-241-301-216-260-7-244-192-147-10-295-142-
Is this dataset a sample or a population?
find the mmean and median of the flight time?
Find the range and quartile range of the flight times.

The apollo space craft program lasted from 1967 to 1972 and incl 13 missions. The missions lasted from as little as 7 hrs to as long as 301 hrs. The duration of each flight is listed below:
9-195-241-301-216-260-7-244-192-147-10-295-142-
Is this dataset a sample or a population?
It is the population of the set of flights described.
It is a sample from the set of all space flights.
---------------------------------------------------------
find the mmean and median of the flight time?
mean: add the numbers and divide by 13 to get 166.08
median is the middle number after putting the numbers in order: 195
Find the range and quartile range of the flight times.
range = max-min = 301-7 = 294
-----------------
I'll leave quartile range to you.
