True or false.

For a sample size of n= 26 and a population parameter of p= 0.6, a normal curve can be used to approximate the binomial probability histogram.

(I'm almost positive its true but I just wanted to double check, thanks! )

I would say it's true, although the criteria are marginal.
I prefer n>=30, and np>10 and nq>10.
Here n=26, nq=10.4.

ok awesome thanks, what got me confused is previously i read its nearly impossible to estimate a population parameter which made me a little bit confused

If you actually run into a problem like that, do not forget the continuity correction.
