I need help!

A random sample is to be selected from a population that has a proportion of successes p. (a) For which of the following sample sizes would the sampling distribution of p be approximately normal if p = 0.85? (Select all that apply.) On = 10 On = 40 On = 80 n = 90 n = 100 n = 400 X (b) For which of the following sample sizes would the sampling distribution of p be approximately normal if p = 0.3? (Select all that apply. ) On = 10 n = 40 On = 80 On = 90 On = 100 On = 400
