a random-number generator is supposed to produce a sequence of 0s and 1s with each value being equally likely to be a 0 or a 1 and with all values being independent. in an examination of the random-number generator, a sequence of 50,000 values is obtained of which 25,291 are 0s. formulate a set of hypotheses to test whether there is any evidence that the random-number generator is producing 0s with probability 0.5. please find the p-value.
