In a binomial experiment with 8 trials and a probability of success p = P(S) = 0.53, give the probability that x = 4 (round to 3 significant digits). [:1 Round the next 3 questions to two places after the decimal. What is the mean (expected value) of x in such an experiment? What is the variance of x? :1 What is the standard deviation of x? :1 Assume that 12% of the world's population speaks English as their native language. If we randomly select 12 people from anywhere in the world, what is the probability that 5 of them speaks English natively? (Round to 3 significant digits.) :] Round the next 3 questions to two places after the decimal. What is the mean (expected value) number of native English speakers in such an experiment? :] What is the variance of the number of native English speakers in such an experiment? :] What is the standard deviation of the number of native English speakers in such an experiment? :]
