In murder trials in 20 Florida counties during 1976 and 1977, the death penalty was given in 19 out of 151 cases in which a white killed a white, in 0 out of 9 casesin which a white killed a black, in 11 out of 63 cases in which a black killed a white and in 6 out of 103 in which a black killed a black. (M. Radelet, Amer. Sociol. Rev.,46:918-927, 1981). These numbers are displayed in the following three-way contingency table (you should be able to create this contingency table yourself),stratified by victim's race.Victim's RaceWhiteBlackTOTALDefendant's RaceWhiteBlackWhiteBlackWhiteBlackDeath Penalty19111061917No death penalty13252997141149TOTAL151639103160166 Now, calculate the odds ratio to examine the marginal relationship between defendant's race and death penalty. Give your answer to three decimal places.

III. In a sample of 20 kaing of mangoes, each containing 50 mangoes, the vendor found that 5, 8, 12, 3, 0, 6, 11, 7, 5, 4, 2, 9, 4, 2, 7, 9, 3, 6, 5, and 2 mangoes respectively are rotten.
Country A and its neighboring Country B are very competitive, both claiming that a higher percentage "smart" people. So an experiment is conducted. A "smart" test is given to random samples in each country. Here are the results... Total Tested Number who were "smart" Country A 100 80 Country B 100 85 Based on these samples, Country B claims superiority. A social media frenzy ensues! For the purposes of this problem, assume that Country A and Country B actually have the same percentage of smart people, and that the results above -- seeming to favor Country B -- were just a result of random differences in sampling. Under that assumption, if the experiment were conducted again (100 new randomly selected people from each country), find the probability that Country B would once again "win" by 5% or more. Round to three decimal places, for example 0.286
I. There are 8 different fruity flavors in Brach's Sweet and Sour Variety Mix. The manufacturer says that a package contains about 280 pieces. You bought a bag to give out for Halloween. a) Your favorite flavor is LemonHead – how many LemonHead pieces do you expect to find in this bag? b) If it turns out that there 40 LemonHeads in the bag do you think the difference between what occurred and what you would expect by chance is statistically significant? Explain. c) If it turns out that there are 70 LemonHeads in the bag do you the difference between what occurred and what you would expect by chance is statistically significant? Explain.
We want to know if the average rating of attractiveness (1=homely, 5=stunning) of a typical person differs depending on the state they are located in. We believe that there will be significant differences in the average attractiveness of the people at each of the four states we examine. 1) Report (in words or statistical notation), our null and alternative hypothesis: Provided are the data we collected from four different states: OR, WA, ID, and CA (see below): OR WA ID CA X bar 3.01 3.07 2.88 3.7 SD 0.42 0.60 0.46 0.30 n 10 10 10 9 SS 92.19 97.47 84.84 123.95 2) Given that we have more than two samples, we need to conduct a one-way ANOVA. Conduct the test in order to calculate the F-statistic addressing our hypothesis. Be sure to calculate the grand mean and the between-groups & within-groups mean-squares first (also don’t forget to round to 2 decimal places and report the formulas!!): 3.) Calculate the degrees…
In a survey of 233 people about the operating systems of various devices that they use (cell phone, tablet, laptop, etc.), the following results were obtained: 146 people use an Android device 150 people use an Apple device 79 people use Android and Apple devices 77 people use Android and Windows devices 67 people use an Apple device, but no Windows device 32 people use Android, Apple, and Windows devices 8 people use devices that are not Android, not Apple, and not Windows How many people use a Windows device?

The enrolled student population at Indiana University-Bloomington, both undergraduate and graduate, is 64.9% White, 7.76% Asian, 7.32% Hispanic or Latino, 4.52% Two or More Races, 4.26% Black or African American, 0.0463% American Indian or Alaska Native, and 0.0287% Native Hawaiian or Other Pacific Islanders. Suppose that in a random sample of 250 students, 40 of them are Asian. Suppose we sample another 250 students from this population, what is the expected proportion of Asian students? b. a. C. Suppose we sample another 250 students from this population, what is the standard deviation of the proportion of Asian students? For a sample of 250 students out of this population, what is the probabilty that the proportion of Asian students is between 6% and 8%?
