A random sample of n = 1,300 observations from a binomial population produced x = 356. (a) If your research hypothesis is that p differs from 0.3, what hypotheses should you test? OH: P = 0.3 versus Ha: p # 0.3 OH: p = 0.3 versus Ha: p > 0.3 O H: p # 0.3 versus Ha: p = 0.3 O Ho: p 0.3 O Ho: P = 0.3 versus Ha: p
