The mean is the ratio of the total weight to the total number of containers. Then the mean weight of the containers on this ship is 4.5 tons.
Mean is simply defined as the average of the given set of numbers. The mean is considered one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.
On a container ship, there were 30 small containers that each weighed 3 tons, 20 medium containers that each weighed 5 tons, and 10 large containers that each weighed 8 tons.
The total weight of the small container will be
→ 30 × 3 = 90 tons
The total weight of the medium container will be
→ 20 × 5 = 100 tons
The total weight of the large container will be
→ 8 × 10 = 80 tons
The total weight on the ship will be
Total weight = 100 + 90 + 80
Total weight = 270 tons
The total number of containers will be
Total containers = 30 + 20 + 10
Total containers = 60
Then the mean weight of the containers on this ship will be
[tex]\rm Mean = \dfrac{Total \ weight\ on \ ship}{Total \ number \ of\ containers}\\\\\\Mean = \dfrac{270}{60}\\\\\\Mean = 4.5[/tex]
The mean weight of the containers on this ship is 4.5 tons.
