Consider a binomial distribution with 8 trials. Either use SALT, or look at a binomial probability distribution table showing binomial probabilities for various values of p, the probability of success on a single trial. (a) For what value of p is the distribution symmetric? p = What is the expected value of this distribution? Is the distribution centered over the value? Yes or no (b) For small values of p, is the distribution skewed right or left? right or left (c) For large values of p, is the distribution skewed right or left? right or left
