Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.

(a) Suppose n = 26 and p = 0.36. Can we approximate p̂ by a normal distribution? Why?

np=9.36 nq=16.64

What are the values of μp̂ and σp̂? (Use 3 decimal places.)

(b) Suppose n = 58 and p = 0.36. Can we approximate p̂ by a normal distribution? Why? (Use 2 decimal places.)

np=20.88 nq=37.12

What are the values of μp̂ and σp̂? (Use 3 decimal places.)

The questions in bold is what I really need help with. Thank you!
