Q3 One computer exam center lost partial user profiles. There are three tests which miss the examinee's names. That is, they can not find who took the test. The exam center randomly distributes the three test scores to three users. Define random variable XX the number of user who receives the correct score. 1. Determine the pmf of XX. 2 Find the probability that at least two users receive the correct scores. 3 Calculate the expected value and variance of random variable XX.

Zachary works as a quality control engineer at Ford Motor Company. One of his job responsibilities is estimating the proportion of defective engines coming off a production line. The production line setting allows for a defective rate of 5%. In a periodical quality checkup, Zachary selected 100 engines that came off the production line. What is the chance Zachary will find more than 10 defective engines? The corresponding Z score is _____

Q3 A box contains 6 balls. Two are numbered 4, two are numbered 5, and two are numbered 6. The balls are mixed and one is selected at random. After a ball is selected, its number is recorded. Then it is replaced. If the experiment is repeated many times, find the variance (02) and standard deviation (o) of the numbers on the balls.
Two college roomates have each commited to donating to charity each week for the next year. The roommates weekly incomes are independent of each other. Suppose the amount donated in a week by one roommate is a random variable with mean $30 and standard deviation $10, and the amount donated in a week by the other roommate is a second random variable with mean $60 and standard deviation $20. Part a.) Find the mean and standard deviation of the distrubution of their combined incomes. Part b.) Over the next year (52 weeks), how many weeks would you expect the two roommates combined income to be more than $120 ?
29 percent of all Samsung cell phones are submitted for service while under warranty. Of these, 66 percent can be repaired, whereas the other 34 percent must be replaced with new units. If a company purchases 12 Samsung cell phones, what is the probability that exactly 2 will end up being replaced under warranty? What would the mean number of cell phones being replaced under warranty be? What would be the variance be for the cell phones being replaced by warranty?.
The manager of a restaurant believes that waiters and waitresses who introduce themselves by telling customers their names will get larger tips than those who don't. In fact, she claims that the average tip for the former group is 17% while that of the latter is only 12%. If tips are normally distributed with a standard deviation of 9%. what is the probability that in a random sample of 13 tips recorded from waiters and waitresses who introduce themselves and 13 tips from waiters and waitresses who don't, the mean of the former will exceed that of the latter? Probability =
Choose the correct definition of a random variable from the list below. A random variable is one whose values correspond to a scale with a countable number of values. one that occurs in one of two possible states, labeled success and failure. one that is measured to explain changes in the response variable. one whose values describe the outcome of some chance process. O one whose effect in an experiment cannot be distinguished from the effects of other variables.
