Exam-Style Question on Box PlotsA mathematics exam-style question with a worked solution that can be revealed gradually |
Question id: 555. This question is similar to one that appeared on an IB AA Standard paper in 2021. The use of a calculator is not allowed.
A number of organically-grown carrots were measured (in centimetres) and the results recorded. The following box and whisker diagram shows a summary of the results where L and U are the lower and upper quartiles respectively. The diagram is not drawn to scale.
The interquartile range is 8cm and there are no outliers in the results.
Find the maximum possible value of L.
Hence, find the maximum possible value of U.
