x is a binomial random variable from a binomial experiment with n = 18 and p = 0.7. a. Compute P(x = 12). Show your work. b. Use Excel function "=binom.dist" to get the printout of the probability distribution. See page 66 of the course packet or pages 269-270 of your textbook. Use the binomial probability distribution from part b to calculate P(x ≥ 14). Use the short-cut formula to compute E (x). e. Compute the variance and the standard deviation of x, C. d.

The mean percent of childhood asthma prevalence in 43 cities is 2.21%. A random sample of 30 of these cities is selected. What is the probability that the mean childhood asthma prevalence for the sample is greater than 2.5%? Interpret this probability. Assume that σ=1.22%.

To avoid unpleasant surprises when the statement comes, you try to record all your credit card transactions in a ledger. Unfortunately, you tend to neglect recording about 5% of your purchases. Suppose that last month, you had 25 purchases on your credit card account. When the statement arrives, you count the number of purchases you forgot to record. The random variable X represents the number of unrecorded purchases in a month with 25 transactions. Find the probability that you would record all 25 purchases. 2.98 .2774 1.25 .3526

When X is a binomial random variable, the mean of the probability distribution = np. A jury has 12 people on the jury. If a certain town has a population that is 9 percent a certain race, how many people of that race would you expect would be on the jury if jury selection was random (and every person was equally likely to be on the jury). Round answers to 4 decimal places as needed.
