Choose an American driver at random and let the random variable X be the number of speeding tickets the driver has received in the last two years. The discrete probability distribution of X is shown.
Tickets 0 1 2 3 4 5Probability 0.16 0.32 0.25 0.12 0.09 0.06
1. Verify the two main requirements that make this a legitimate discrete probability distribution.
2. Create a probability histogram for the random variable X.
3. Explain in words what the probability P(X) means. What is the probability P(X)?
4. Write the mathematical expression of the event that a randomly chosen driver has more than three speeding tickets in terms of the random variable X. What is the probability of this event?
5. Compute and interpret E(X), the expected value of the random variable X.
Evaluate the factor effects. Find out which factors are significant in explaining yield.

Construct a 90% two-sided confidence interval onthe difference between the proportion nonconforming in processes 1 and 2. Based on this confidence interval, can you conclude at a significance level of 10% that the difference is not equal to 10%? W..
Hamburger Joe's sells the best burgers in town. The variable unit cost for making one burger is $.97. The fixed cost of making burgers for 12 months will be a total of: $140,000.
At the .05 significance level, can we conclude that there is a difference in their mean times?
One of the most famous probability calculations is called the "birthday problem". In probability theory, the birthday problem or birthday paradox concerns the probability that, in a set of n randomly chosen people
Suppose there are two samples of size 6 and 7, with a rank sum of 58 in the sample of size 6. Using the Wilcoxon rank sum test, evaluate the significance of the results, assuming there are no ties.
It has been claimed that women live longer than men; however, men tend to be older than their wives. Ages of sixteen husbands and wives from England were obtained. These data should be analyzed with a
