The binomial distribution can be used to model situations where a) A researcher is observing the number of occurences of an event of interest in a specified time period. b) a ressearcher is observing the number of events occuring out of a set number of opportunities for that event to occur. c) A researcher is observing the specified number of events occuring in a specified area. d) A researcher is recording the number of events that fall into a number of different categories. For the exact binomial test, we are using the binomial distribution assuming ____________________ to compute the probability of observing the equal number of successes or more extreme number of successes
