A Iandom sample ofn = 1,400 observations from a binomial population produced x = 382. (a) If your research hypothesis is that p differs from 0.3, what hypotheses should you test? O H0: ,0 = 0.3 versus Ha: p 0.3 O H0: ,0 0.3 q! (b) Calculate the test statistic and its p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.) 2= E
