Fernando et al. (A-3) studied drug-sharing among injection drug users in the South Bronx in NewYork City. Drug users in New York City use the term "split a bag" or "get down on a bag" to refer tothe practice of dividing a bag of heroin or other injectable substances. A common practice includessplitting drugs after they are dissolved in a common cooker, a procedure with considerable HIV risk.Although this practice is common, little is known about the prevalence of such practices. Theresearchers asked injection drug users in four neighborhoods in the South Bronx if they ever"got down on" drugs in bags or shots. The results classified by gender and splitting practice aregiven below:GenderMaleFemaleSplit Drugs349220Never Split Drugs324128Refer to the data calculate:(a) P(Malen Split Drugs)(b) P(Male U Split Drugs)(c) P(Male | Split Drugs)(d) P(Male)TotalTotal569Source: Daniel Fernando, Robert F.

A researcher was studying how much electricity (in kilowatt hours) people in Spain and Germany used in their homes last year. The researcher took a random sample of people from each country to test if the average electricity usage was significantly different. Here is a summary of their results: Electricity usage Country Mean StDev SE mean Spain 100 1780 415 41.5 Germany 100 1690 405 40.5 95% CI for us - PG: 90 + 114.4 The researcher wants to use these results to test Ho: µs = PG versus H: µs # pG. Assume that all conditions for inference have been met. Based on the interval, what do we know about the corresponding P-value and conclusion at the a = 0.05 level of significance? The P-value is less than a=0.05, and they should conclude that there is a difference between the means. The P-value is less than a=0.05, and they cannot conclude that there is a difference between the means. The P-value is greater than a=0.05, and they cannot conclude that there is a difference between the means.…

A bag of candy contains 5 different types of colored candies; red, green, blue, yellow, and orange. According to the manufacturer, bags should contain an equal number of each color. Students in a statistics class decided to use a chi-square procedure to test the manufacturer’s claim. They opened a bag of candy and recorded the number of candies of each color. The results are shown in the following table. Red Green Blue Yellow Orange 17 24 20 25 14 Which color contributes most to the chi-square test statistic? Red A Green B Blue C Yellow D Orange
I NEED THE ANSWER TO THE "NUMBER OF DUMMY VARIABLES" A manager of a local package delivery store believes that too many of the packages were damaged or lost.

A college student is interested in whether presoaking time has an effect on cleanliness of clothing. He collects the dirty clothes from all of the people in his dorm and randomly assigns clothing to one of four presoak time conditions: 5 minutes, 10 minutes, 15 minutes, 20 minutes. He then asks members of another dorm to rate the cleanliness of the items (they don’t know which clothing got which soaking time). The data are presented below. C) Perform an LSD test and answer the questions that follow (SHOW ALL WORK!!! This can be on the same page as your other ANOVA hand work.

A local health department believes that a store is merchandising its cereal aisle in a way that puts sugary cereal brands at eye level for children. The store claims that it is not considering sugar content and is stocking the shelves based on other factors. An inspector visited the store and recorded the sugar content per serving listed on the boxes (sugar content for each box is listed under the shelf where that box of cereal is located). Shelf 1 Shelf 2 Shelf 3 Shelf 4 7 13 6 10 8. 5 14 7 8 11 11 10 11 3 a) What are the treatment groups, and how many experimental units are there per treatment? b) If instead of using the content listed on the box, the inspector sampled from multiple boxes of each brand of cereal and tested them for sugar content. How many experimental units were there be if there were 10 boxes per brand on the shelf? Explain your answer. [hint: all the boxes for each brand will be in one place] c) State the null hypothesis and create an ANOVA table based on sugar…
