Your work in openintro is wonderful, and your videos are amazing. I'm a PhD student improving my statistics base with OpenIntro Statistics. Thank you very much for your help and please don't stop making it.

Have a question on 5.6b repeated student samples in this chapter of 5.1. Can we expect that the distribution is normal only when np and n(1-p) is equal or greater than 10? Because in 5.6, 0.16(0.4) does not result in a number greater than 10.

In the diagram of the normal distribution with mean 0.88, why was the two other points .86 and .90?
