Awebsite reports that 70% of their users are from outside the United States and that 40% of their users iog on to their webs'ne every day. Suppose that 15% of their users are United States users who log on every day Complete parts a through e below. a) What percentage of the website's users are from the United States? The percentage of the website's users that are from the United States is %. b) Whattype of probability is the 15% mentioned above? 0 empiricai probabiiity O marginai probabiiity 0 joint probability 0 personai probabiiity c) Construct a contingency table showing ali thejoint and marginal probabilitia Assign user from the United States and users from outside the United States to the columns. Assign users who log on every day user and users who do not iog on every day to the rows. United Not United States States \"m\" Log on every day Do not log on every day Total (Do not round) d) What is the probability that a user is from the United States given that he or she logs on every day? The probability that a user is from the United States given that he or she iogs on every day is (Round to three decimai places as needed) eJAre From United States and Log on Every Day independent? Expiain. Choose the correct answer beiow O A. Yes. because the conditional probability that the individuai is from the United States given they log on every day is not equal to the probabii'y the individual is from the Uned States. 0 B. Yes. because the conditional probability that the individuai is from the United States given they log on every day is equai to the probability the individual is trom the United Stats. 0 C. No, because the conditional probability that the individual is from the United States given they log on every day is not equal to the probability the individuai is from the United Stats 0 D. No, because the conditional probability that the individual is from the United States given they log on every day is equal to the probability the individual is from the United States
