Median:30

Mode:42

Range:36

Answer 2

Answer:

Mean $=28\dfrac{11}{15}$

Median $=30$

Mode $=42$

Range $=36$

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. The total number is 862 cans, there are 30 numbers, then the mean is

$\text{Mean}=\dfrac{862}{30}=28\dfrac{11}{15}$

The median is the value separating the higher half from the lower half of a data sample. There are 30 numbers in the sample, hence the median is the average value between 15th and 16th numbers:

$\text{Median}=\dfrac{30+30}{2}=30$

The mode is the value that appears most often. Number 42 appears most often, so

$\text{Mode}=42$

The range is the difference between the maximum and minimum numbers in the sample, so

$\text{Range}=43-7=36$
