Why does this man know every subject ever

[stephenbenecke]

A solid video, thanks. There's certainly more discussion to follow, exploring (b) further and I understand why you stopped short lol. Professionally, I believe the issue with b vs c is about how technical we wish to get with the definition/meaning of the word "probability". Or how technical we NEED to get to understand basic statistics, and what the common intuitive understanding of the probability concept of the audience is.

It's strange that choice C is correct regardless of any numbers given in the problem statement, except 90%. It would be helpful to understand how to interpret the numbers given...what practical use does the 341 to 359 range have in this single study?

[getvasued]

Someone please explain why option B is wrong?

[goroth]

This is a poorly written question. Options B and C are both correct, despite your 'discomfort' about option B. Saying that the population mean has a 0.9 probability of being inside the confidence interval is equivalent to saying that the confidence interval has a 0.9 probability of capturing the population mean.

[voteforno.]

Answer "B" is definitely incorrect. It's not that it's the "more correct" answer. "B" is simply wrong.
