Assume a poisson random variable has a mean of 6 successes over a 120-minute period a. find the mean of the random variable, defined by the time between successes mean b. what is the rate parameter of the appropriate exponential distribution? (round your answer to 2 decimal places.) rate parameter c. find the probability that the time to success will be more than 60 minutes. (round intermediate calculations and final answer to 4 decimal places.) probability

Design an er diagram for keeping track of information about votes taken in the u.s. house of representatives during the current two-year congressional session. the database needs to keep track of each u.s. state's name (e.g., texas', new york', california') and include the region of the state (whose domain is {northeast', midwest', southeast', southwest', west'}). each congress person in the house of representatives is described by his or her name, plus the district represented, the start date when the congressperson was first elected, and the political party to which he or she belongs (whose domain is {republican', democrat', 'independent', other'}). the database keeps track of each bill (i.e., proposed law), including the bill name, the date of vote on the bill, whether the bill passed or failed (whose domain is {yes', no'}), and the sponsor (the congressperson(s) who sponsored - that is, proposed - the bill). the database also keeps track of how each congressperson voted on each bill (domain of vote attribute is {yes', no', abstain', absent'}). additional information:
