Answer: According to Study Island the answer is 65
Explanation:
In order to determine the outlier value, create a box plot.
To create a box plot, order the data.
5, 7, 8, 8, 9, 10, 12, 14, 15, 15, 19, 21, 23, 25, 26, 26, 27, 29, 30, 32, 32, 35, 40, 60, 65
Find the median, the first quartile (Q1), the third quartile (Q3), and the interquartile range (IQR).
Median = 23
Q1 =
10 + 12
2
= 11
Q3 =
30 + 32
2
= 31
IQR = Q3 - Q1 = 31 - 11 = 20
Find the upper and lower fences for the given data.
Lower Fence = Q1 - 1.5 × IQR
= 11 - 1.5 × 20
= -19
Upper Fence = Q3 + 1.5 × IQR
= 31 + 1.5 × 20
= 61
