In a poll, respondents were asked whether they had ever been in a car accident. 157 respondents indicated that they had been in a car accident and 117 respondents said that they had not been in a car accident. If one of these respondents is randomly selected, what is the probability of getting someone who has been in a car accident?
The data set represents the income levels of the members of a country club. Find the probability that a randomly selected member earns at least $88,000
total, 14 of them at or above $88,000 means the probability is:
In a certain class of students, there are 15 boys from Wilmette, 5 girls from Kenilworth, 9 girls from Wilmette, 6 boys from Glencoe, 2 boys from Kenilworth and 8 girls from Glencoe. If the teacher calls upon a student to answer a question, what is the probability that the student will be from Kenilworth?
Kids from Kenilworth / Total number of kids
(5 + 2) / (15+5+9+6+2+8) = 7/45 = .156
4. Find the probability of correctly answering the first 2 questions on a multiple choice test if random guesses are made and each...
Probability Probabilities according to Becker and Parker (2011) are used in both simulations and real life scenarios to help in the estimation of the occurrence of events. In the words of Gravetter and Wallnau (2008), "for a situation in which several different outcomes are possible, the probability for any specific outcome is defined as a fraction or a proportion of all the possible outcomes." In that regard, chance and randomness are
6, and the chances of rain is 0.4. Historical data may be used for forecasting, but past patterns will not necessarily be reliable. To gain a more reliable assessment there are alternatives; the weather service makes advanced forecasts based on a large amount of data. However, to gain this information the business will have to pay a fee. This means that there is a cost associated with gaining the more accurate

Looking at the variability of each group is important because it gives the decision-maker an indication of how wide is the spread of scores of each worker in the group. That is, through measures of variability, the decision-maker is informed of just how varied the manual dexterity scores of the workers are, since it would be most efficient for him/her to have workers who at least have the same levels/scores
measure situations of reality (Piquero, 2002). A dependent variable and an independent variable are studied for patterns of relation, covariance, and cause and effect. For example, the relationship between impulsivity, the independent variable, and criminal behavior, the dependent variable, or the effects of a mandatory arrest policy, the independent variable, on future patterns of domestic violence, the dependent variable, are both examples of quantitative research. For causality, three criteria
