Consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis test? O A Ho: P = P2 OB. Ho: Py* P2 C. Ho: P42P2 HP, P2 H:PP2 H: P1 P2 D. Ho PP2 OE Ho: P, P2 OF Ho: P4 SP2 HP P2 MA: P1 P2 HP1 P2 Identify the test statistic z= 0.85 (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.)
