What is the conclusion of the hypothesis test? O A. Reject Ho; the data do not provide sufficient evidence to conclude that p *0.7. B. Do not reject Ho; the data do provide sufficient evidence to conclude that p #0.7. OC. Do not reject Ho; the data do not provide sufficient evidence to conclude that p *0.7. D. Reject Ho; the data do provide sufficient evidence to conclude that p *0.7. O E. The one-proportion z-test is not appropriate.
