In a certain​ survey, people chose to respond to this​ question: "Should passwords be replaced with biometric security​ (fingerprints, etc)?" Among the​ respondents, ​% said​ "yes." We want to test the claim that more than half of the population believes that passwords should be replaced with biometric security. Complete parts​ (a) through​ (d) below. a. Are any of the three requirements​ violated? Can a test about a population proportion using the normal approximation method be​ used? A. The conditions np5 and nq5 are not​ satisfied, so a test about a population proportion using the normal approximation method cannot be used. B. The sample observations are not a random​ sample, so a test about a population proportion using the normal approximating method cannot be used. C. One of the conditions for a binomial distribution are not​ satisfied, so a test about a population proportion using the normal approximating method cannot be used. D. All of the conditions for testing a claim about a population proportion using the normal approximation method are​ satisfied, so the method can be used.
