Anne has the following data: 13, 16, z, 8, 11 If the median is 13, which number could z be? Choices: (A)9 (B)14

Understand median concept: Understand the concept of median. The median is the middle value in a list of numbers sorted in ascending order. Since there are 5 numbers, the median will be the third number when sorted. Sort and analyze numbers: Sort the given numbers, excluding z, and analyze the possible positions for z. The sorted numbers without z are 8, 11, 13, 16. To have a median of 13, z must be placed in such a way that 13 remains the third number in the sorted list. Determine possible values for z: Determine the possible values for z. If z is less than 13 but greater than 11, it will not affect the position of 13 as the median. If z is greater than 13 but less than 16, 13 will still be the median. Therefore, z can be any number between 11 and 16, excluding 13 itself. Check choices for z: Check the given choices for z. The choices are: (A) 9 (B) 14 Since 9 would place z before 11, making 11 the third number, it cannot be the median. However, 14 fits between 13 and 16, keeping 13 as the median.

Understand median concept: Understand the concept of median. The median is the middle value in a list of numbers sorted in ascending order. Since there are $5$ numbers, the median will be the third number when sorted.
Sort and analyze numbers: Sort the given numbers, excluding $z$ , and analyze the possible positions for $z$ . The sorted numbers without $z$ are $8$ , $11$ , $13$ , $16$ . To have a median of $13$ , $z$ must be placed in such a way that $13$ remains the third number in the sorted list.
Determine possible values for $z$ : Determine the possible values for $z$ . If $z$ is less than $13$ but greater than $11$ , it will not affect the position of $13$ as the median. If $z$ is greater than $13$ but less than $16$ , $13$ will still be the median. Therefore, $z$ can be any number between $11$ and $16$ , excluding $13$ itself.
Check choices for $z$ : Check the given choices for $z$ . The choices are: $\newline$ (A) $9$ $\newline$ (B) $14$ $\newline$ Since $9$ would place $z$ before $11$ , making $11$ the third number, it cannot be the median. However, $14$ fits between $13$ and $z$ $0$ , keeping $13$ as the median.
