Answer:
Yes, 7.5 and 9.2 are outliers
Step-by-step explanation:
Given the 5 number summary :
Minimum: 1.8
Q1: 3.3
Median: 3.8
Q3: 4.5
Maximum: 9.2
To detect an Outlier use the Relation :
Lower bound : Q1 - 1.5*IQR
IQR = Q3 - Q1 = 4.5 - 3.3 = 1.2
lower bound : 3.3 - 1.5(1.2)
Lower bound = 3.3 - 1.8 = 1.5
Upper bound : Q3 + 1.5*IQR
Upper bound : 4.5 + (1.5 * 1.2)
Upper bound : 4.5 + 1.8 = 6.3
Hence,
1.5≤ x ≤ 6.3
Songs with length 7.5 and 9.2 do not meet the condition and are this outliers
