The use of statistics is often employed to highlight international, national, and state trends in crime and drug abuse.1. Explain the following terms in your own words.1. Box-and-whiskers plot2. Standard deviation3. Normal distribution (9 points)2. A BAC describes the amount of alcohol in a person's blood, expressed as weight of alcohol per unit of volume of blood. For example, 0.08 percent BAC indicates 80 mg of alcohol per 100 ml of blood." (source: http://www.austintexas.gov/faq/what-does-blood-alcohol-concentration-bac-measure (Links to an external site.); please note, you do not require to access the source to answer the question) For the data set below calculate the mean, median, mode and standard deviation. Then, for Blood alcohol levels only, plot: a. Frequency histogram b. Probability (i.e. cumulative frequency) plot What do you conclude about the distribution of the sample?From the data set presented here, would you feel comfortable to say that the age group between 30-39 years exhibits higher BAC counts than other age groups?

Then, for each of the following three scenarios, list the possible outcome string and calculate the probability of the scenario as a decimal number (to three places) showing all working (9 points).The probability of getting three heads when flipping a coin 3 times.The probability of at least getting one head and one tail when flipping a coin 3 times.The probability of getting a head in the first flip, a tail in the second, and a head again in the third flip of a coin.Below is an incomplete contingency table displaying two levels for each the gender and the political party association (13 points).Complete the table with all marginal totals and cell counts.Calculate the following probabilities.For a male to be a Republican.For a voter to be female.For a voter to be either a democrat or a female.For a person to not be a female but voting democratic.Political partyTotalGenderRepublicanDemocratMale8773?Female61??Total??300

Do you use probability in your profession or real life? You most likely do. For example, the chance of rain tomorrow is 27%. We hear similar probabilities in the media all the time. Similar probabilities could be found in other professions. Complete one of the following:(i) Find an example of probability involving “A or B” that is used in your chosen profession or real life. Explain the example. Are the events A and B in your example mutually exclusive? Which Addition Rule formula for P(A or B) applies? Be sure to cite the source of the information clearly.(ii) Using a search engine, find an example of probability involving “A and B” that is used in your chosen profession or real life. Explain the example. Are the events A and B in your example independent? Which Multiplication Rule formula for P(A and B) applies? Be sure to cite the source of the information clearly.(iii) Find an example involving conditional probability that is used in your chosen profession or real life. Explain the example. Be sure to cite the source of the information clearly.

For this activity, utilize the five-step process and the following data set. The two populations are: Population A: oMean=36, SD=4 Population B: o(sample of one): Raw Score=44 Set up a one-tail Z test evaluating the improvement of a score, presenting the following: Restate the research question as a research hypothesis and a null hypothesis about the populations.Determine the characteristics of the comparison distribution.Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected.Determine your sample’s score on the comparison distribution. 5.Decide whether to reject the null hypothesis.
