A random sample of n = 1,000 observations from a binomial population contained 385 successes. You wish to show that p < 0.4. State the null and alternative hypothesis. H0: p < 0.4 versus Ha: p > 0.4 H0: p ≠ 0.4 versus Ha: p = 0.4 H0: p = 0.4 versus Ha: p < 0.4 H0: p = 0.4 versus Ha: p > 0.4 H0: p = 0.4 versus Ha: p ≠ 0.4 Calculate the appropriate test statistic. (Round your answer to two decimal places.) z = Provide an α = 0.05 rejection region. (Round your answer to two decimal places. If the test is one-tailed, enter NONE for the unused region.) z > z < State your conclusion. H0 is not rejected. There is insufficient evidence to indicate that p is less than 0.4. H0 is rejected. There is insufficient evidence to indicate that p is less than 0.4. H0 is not rejected. There is sufficient evidence to indicate that p is less than 0.4. H0 is rejected. There is sufficient evidence to indicate that p is less than 0.4.
