    I am having problem with this questions...

    6% of the elderly men are tall (2.0 feet). Yet, their middle-aged offsprings, 15% of them are the same height (2.0 feet). What is wrong with the conclusion from these data that being tall is bad for longevity?

    If I'm understanding this correctly, I think what the question is saying:
    "15% of middle-aged offspring from the 6% elderly ended up being 2 meter tall"

    So of the 94% elderly only 6% ended up being 2 meter tall, but it doesn't say the percentage of elderly that is taller than 2 meter or shorter than 2 meter... It might be possible that of the 100 elder, there are 6 elder who are 2 meter tall, then instead, 100% of them are still alive.
    There are not information to understand whether or not that height has a correlation with longevity.

    The 2nd part where "15% of middle-aged offspring", this information is unimportant, it has no conflict with the elder non longevity
    Unless if it state that 15% of middle-aged who are 2 meter tall, but only 1% becomes elder than we might have more information

    *Not sure if I'm right -_-
