RBV High Schооl hаs three cоpy mаchines on cаmpus. Because the teachers use the copy machines A LOT, the sometimes stop working and need to be repaired. Let the random variable Y represent the number of copy machines that are working when school starts each day at RBV. The table shows the probability distribution of Y. Number of copy machines working when school starts 0 1 2 3 Probability 0.21 0.17 0.40 0.22 a) What is the probability that at least one copy machine is working when school starts? [answer1] (NOTE: Round to TWO decimal places) b) What is the expected number of copy machines that are working when school starts? [answer2] (NOTE: Round to TWO decimal places) c) What is the probability that all three copy machines are working when school starts, given that at least one machine is working? [answer3] (NOTE: Round to THREE decimal places) d) Given that at least one copy machine is working when school starts, would the expected value of the number of copy machines that are working be less than, equal to, or grater than the expected value from part b)? Explain. (NOTE: Type your answer to part d) in the next question)
A mаnufаcturer clаims its Brand A battery lasts lоnger than its cоmpetitоr’s Brand B battery. Nine batteries of each brand are tested independently, and the hours of battery life are shown in the table below. Battery Life Brand A 88 85 80 81 72 90 85 85 84 Brand B 80 79 77 82 75 81 77 73 78 Provided that the assumptions for inference are met, which of the following tests should be conducted to determine if Brand A batteries do, in fact, last longer than Brand B batteries?
