Understanding Sample Proportions and the Binomial Distribution

Click For Summary
SUMMARY

This discussion centers on understanding sample proportions and the binomial distribution in the context of a statistical problem. The user calculates sample proportions for a dataset, yielding results of 0.8654, 0.01407, and 0.9577 for various parts of the question. The inquiry specifically addresses the need for clarity on the binomial distribution and its application to sample proportions, particularly regarding the ZikaCheck results. The conversation emphasizes the importance of grasping the binomial distribution when analyzing proportions related to two outcomes.

Hi,

I am doing a past paper but I am kinda stuck on one of the questions.

These are the answers I have:
2a. 225/260 = 0.8654
2b. 32/260 * 4/32 = 0.01407
2c. 32/260 * 28/32 + 228/260 * 221/228 = 0.9577

Then for 2d, I have no idea what to do. Am i suppose to draw one of those probability distribution table? And what does it mean sample proportion of accurate ZikaCheck result?

Thank you very much.

Hi smallso,

Have you covered the binomial distribution? Usually when we talk about proportions that are related to two outcomes this involves this distribution. Does that sound familiar?
