Question

key: 1 | 8 represents a species of turtle whose average lifespan is 18 years. five - number summary min q1 median q3 max 13 24 30 40 138 according to the 1.5·iqr rule for outliers, how many high outliers are there in the data set? choose 1 answer: a 0 b 1 c 2 d 3

Explanation:

Step1: Calculate the inter - quartile range (IQR)

IQR = $Q_3 - Q_1$. Given $Q_1 = 24$ and $Q_3 = 40$, so IQR = $40 - 24=16$.

Step2: Calculate the upper fence for outliers

The upper fence for outliers is given by $Q_3+1.5\times IQR$. Substitute the values: $40 + 1.5\times16=40 + 24 = 64$.

Step3: Identify high outliers

We check the maximum value ($max = 138$) against the upper fence. Since $138>64$, there is 1 high outlier.

Answer:

B. 1
