In a sample of 50 mice, a biologist found that 46% were able to run a maze in 30 seconds or less. Find the 90% limit for the population proportion of mice who can run that maze in 30 seconds or less.

Hello lwebb !

Well : how have you approached this homework question so far?
Have you drawn your curve based on the provided data?
Have you checked your formula for a 90% limit?
Just tell me what you got so far, and I'll help you to the proper solution.

Here is a LINK to a website that provides all the information you require to solve the question yourself. (http://www.netmba.com/statistics/distribution/normal/)

The idea of homework questions is that YOU do them, so that YOU learn from them...

Just post your data here. If needed, contact me (leftclick on my handle and forward a private message).
