Final answer:
The provided exercise asks about the upper inner and outer fences for a box plot, but not enough information is given to calculate these values since the third quartile (Q3) is not provided.
Step-by-step explanation:
The question refers to the calculation of the upper inner and outer fences in the context of a box plot, which are methods used to identify outliers in a dataset. To address the question correctly, we need both the first quartile (Q1) and third quartile (Q3) values, along with the interquartile range (IQR). The IQR is calculated as Q3 - Q1. The upper inner fence is defined as Q3 + 1.5 × IQR, and the upper outer fence is Q3 + 3 × IQR.
However, since the provided information only gives us the value for the 25th percentile (which corresponds to Q1), we cannot calculate the fences without the third quartile (Q3). Therefore, we cannot address which statement regarding fences is incorrect. More information is required to perform these calculations and determine the accuracy of statements A through D.
Awaiting time of 70 minutes being an outlier cannot be confirmed without the complete information to determine the upper fences accurately.
