Answer:
Mean = 7.3, Median = 7, Mode = 1
Explanation:
Given the set of numbers below:
[tex]\begin{equation}7,3,2,1,13,8,1,5,14,11,15\end{equation}[/tex]
We want to find the mean, median, and mode.
First, begin by sorting the data in ascending order.
[tex]1,1,2,3,5,7,8,11,13,14,15[/tex]
(a)Mean
There are 11 items in the dataset.
To find the mean, add the numbers and divide by 11.
[tex]\begin{gathered} Mean=\frac{1+1+2+3+5+7+8+11+13+14+15}{11} \\ =\frac{80}{11} \\ =7.27 \\ Mean\approx7.3 \end{gathered}[/tex]
(b)Median
The median is the number in the middle when arranged in ascending order.
The number in the middle is 7, therefore:
Median = 7
(c)Mode
The mode is the number that appears the most.
Mode = 1
The second option is correct.
