Question 6 1 pts Suppose we are flipping a fair coin (i.e., probability of heads = 0.5 and probability of tails = 0.5). Further, suppose we consider the result of heads to be a success. What is the mean of the binomial distribution if we flip the coin 5 times?

Question 7 1 pts Suppose we are flipping a fair coin (i.e., probability of heads = 0.5 and probability of tails = 0.5). Further, suppose we consider the result of heads to be a success. What is the standard deviation of the binomial distribution if we flip the coin 5 times?

Question 8 1 pts Suppose we are flipping a fair coin (i.e., probability of heads = .5 and probability of tails = .5). What is the probability that in a sample of 5 flips, all 5 will be heads?

Question 9 1 pts Suppose we are flipping a fair coin (i.e., probability of heads = .5 and probability of tails = .5). What is the probability that in a sample of 5 flips, fewer than 4 will be heads?

Question 10 1 pts The U.S. mint, which produces billions of coins annually, has a mean daily defect rate of 4 coins. Let X be the number of defective coins produced on a given day. What is the variance of this distribution?

Question 11 1 pts The U.S. mint, which produces billions of coins annually, has a mean daily defect rate of 4 coins. Let X be the number of defective coins produced on a given day. On a given day, what is the probability of exactly 4 defective coins?

Question 12 1 pts The U.S. mint, which produces billions of coins annually, has a mean daily defect rate of 4 coins. Let X be the number of defective coins produced on a given day. On a given day, what is the probability of 3 or fewer defective coins?

Question 13 1 pts The U.S. mint, which produces billions of coins annually, has a mean daily defect rate of 4 coins. Let X be the number of defective coins produced on a given day. On a given day, what is the probability of more than 3 defective coins?
