The five-number summary is 3,7,15,19,25 ; option B
Here, we want to get the five number summary
These are values that typically descibes the set of values
What we need in the 5 number summary are;
1) Minimum value
2) First quartile
3) Median
4) Second quartile
5) Maximum value
1)The minimum value is the smallest value of the set which is 3
2) To get the first quartile, we use the formula below, where n represents the number of values in the set = 7
[tex]\begin{gathered} \frac{(n+1)}{4}th\text{ term} \\ \\ \frac{7+1}{4}\text{ = 2nd term} \end{gathered}[/tex]The 2nd term is 7
3) The median is the middle number
In this case, this is 15
4) The second quartile can be calculated with the formula;
[tex]\frac{3(n+1)}{4}\text{ = }\frac{3(7+1)}{4}\text{ = 6th term}[/tex]The sixth term is 19
5) The maximum number is 25
So the five-number summary is;
3,7,15,19,25
