To determine which statement about Jeffrey's data is FALSE, let's analyze each option based on the characteristics of a boxplot:
A. **The mean of the data is 40.**
- A boxplot provides information about the median, quartiles, and potential outliers, but it does not provide the mean directly. Thus, we cannot ascertain whether the mean being 40 is true or false without additional data.
B. **80 is an outlier.**
- Boxplots typically indicate outliers, which are values that fall outside the fences established by the interquartile range (IQR). If 80 is presented as an outlier in the boxplot, then this statement can be true. However, we cannot confirm this without seeing the boxplot.
C. **The minimum of the data is 10.**
- The minimum is represented as the leftmost point (if it is not an outlier) on the boxplot. If the boxplot shows 10 as the minimum, this statement is true.
D. **The interquartile range is around 24.**
- The interquartile range (IQR) is calculated as Q3 - Q1. Without the specific values of Q1 and Q3 from the boxplot, we cannot confirm whether the IQR is around 24.
Without the visual of the boxplot, we can only preliminarily evaluate the statements. Generally, options A, B, and D are ambiguous without further context from the boxplot.
If you have access to those specific values or the boxplot, it will be easier to determine which statement is actually false. However, typically, one of these will often turn out to be incorrect in the data interpretation. If forced to pick one based on a common misconception around data, I would suspect option A (about the mean being 40) is a likely candidate for being false, as boxplots do not typically provide mean values, while options regarding minimums and outliers can be verified against the plot.
Thus, proceed with caution because definitive evaluation requires the boxplot visual!
