Are any of the thr O A. All of the condions for testing a claim about a population proportion using the normal approximation method are safisfied, so the method can be used the popuíation believes that passwords should be replaced with biometric security Complete parts (a) ee requirements violated? Can a test about a population proportion using the normal approximation method be used? O B. One of the conditions for a binomial distribution are not satisfied, so a test about a population proportion using the normal appraximalting method cannot be used are not a random sample, so a test about a population proportion using the normal approximating method cannot be used O D. The condtions np 25 and nq a 5 are not satisfied, so a test about a population proportion using the normal approximation method cannot be used t was stated that we can easily remember how to interpret P-values with this. "If the P is low. the nul must go " What does this mean? O A. This statement means that if the Pivalue is very low, the null hypothesis should be accepted. O B. This statement means that if the P-value is not very low. the nul typothesis should be rejected O C. This statement means that if the P-value is very low, the null hypothesis should be rejected D. This statement means that if the Pivalue is very low, the alternative hypothesis should be rejected Click to select your answer
