You can put this solution on YOUR website! Given a binomial distribution with n = 23 and p = 0.78, would the normal distribution provide a reasonable approximation? Why or why not?
---
If p = 0.78, q = 0.22
---
Then np = 23*0.78 > 5 and nq = 23*0.22 > 5
---
So it is reasonable to use the normal approximation.
