A scatter diagram is useful to determine if a relationship exists between two variables.Enrollment in a particular class for the last four semesters has been 122, 128, 100, and 155 (listed from oldest to most recent). The best forecast of enrollment next semester, based on a three-semester moving average, would be:Consider a standard 52-card deck of cards. The probability of drawing either a seven or a black card is 7/13.A __________ is a numerical statement about the likelihood that an event will occur. variance mutually exclusive construct collectively exhaustive construcOur department store is having a sale on personal computers, of which three are in stock (no rain checks). There is a certain probability of selling none. The probability of selling one is twice as great as the probability of selling none. The probability of selling two is three times the probability of selling none. Finally, the probability of selling all the personal computers is four times as great as the probability of selling none. Using the above information, what is the probability of selling two personal computers? Hint: Let the probability of selling none equal xAn urn contains seven blue and three yellow chips. If the drawing of chips is done with replacement, what is the probability of drawing a yellow chip on the second draw given that a yellow chip was drawn on the first draw.
