Consider a binomial distribution with12trials. Either use SALT, or look at abinomial probability distribution tableshowing binomial probabilities for various values ofp, the probability of success on a single trial.

(a) For what value ofpis the distribution symmetric?

p=

What is the expected value of this distribution?

Is the distribution centered over the value?

Yes

No

(b) For small values ofp, is the distribution skewed right or left?

right

left

(c) For large values ofp, is the distribution skewed right or left?

right

left
