In a certain survey, 508 people chose to respond to this question: "Should passwords be replaced with biometric security (fingerprints, etc)?" Among the respondents, 53% 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. %3D a. Are any of the three requirements violated? Can a test about a population proportion using the normal approximation method be used? O A. The conditions np 25 and nq 25 are not satisfied, so a test about a population proportion using the normal approximation method cannot be used. O B. The sample observations are not a random sample, so a test about a population proportion using the normal approximating method cannot be used. O 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. O D. All of the conditions for testing a…

ANSWER A B C (b)Based on the answer to part (a), choose the correct statement. ___ The value of the test statistic is in the rejection region. ___ The value of the test statistic is not in the rejection region. (c)Based on your answer to part (b), which of the following statements is true at the significance level of 0.10 ? ___The null hypothesis must be rejected. ___The null hypothesis should not be rejected.
Which of the following is not one of the four steps of the hypothesis test? A. State the level of significance, choose a test, and check the conditions for the test B. Make a decision to reject or not reject the null hypothesis C. State the null and alternative hypothesis about the population parameter D. All of the these are steps of the hypothesis test
Determine the second step of hypothesis testing, and explain the procedure and logic of this step. Choose the correct answer below. A. The second step is to figure out the probability of getting a particular result if the research hypothesis is true. In this process, one wants to determine the probability of getting a sample score as extreme as the one found if the sample were from a population with a distribution corresponding to the research hypothesis being true. B. The second step is to determine if the test should use a directional hypothesis or a nondirectional hypothesis. Once this is determined, the correct cutoff sample scores can be obtained. C. The second step is to determine the characteristics of the comparison distribution. The overall logic of hypothesis testing involves figuring out the probability of getting a particular result if the null hypothesis is true. In this process, one wants to determine the probability of getting a sample score as…
