This question is... just, wow. Where do I even begin?

"An orange-juice processing plant receives a truckload of oranges. The quality control team randomly chooses three pails of oranges, each containing 50 oranges, from the truckload. Identify the sample and the population in the given scenario.

StateThe statistic doesn't quite make sense (5% implies 7.5 oranges were unsatisfactory?). State one conclusion? I mean, I'm sure there areoneconclusion that the quality control team could make about the population if 5% of the sample was found to be unsatisfactory."

**lots**of things one could say about the oranges. I'm not sure how any of the conclusions could be statistical in nature. Also, I don't understand how this is a 2-pointer. Seems like the second task should be more substantial, but not on a question worth so few points. What exactly were they looking for here? Of course, the scoring rubric and sample responses are of no use whatsoever.

What's one conclusion that can be made about the quality of the writing of A2 Regent's exam questions? I can think of a few...no z-scores or CIs needed!
