Your response should be 400-750 words, in APA format, 12pt font, 1" margins, references page, etc. (abstract not required). Make sure to use a .doc, docx, or rtf file format and attach the file when submitting. Also, these assignments have a minimum of five (5) required sources. While the source report can count as one source, this means you need to find additional sources to add detail and support to your answers. Look for real world examples in the news, peer reviewed journals, etc. For more information about the assignments, refer to the assignment and its grading rubric on Blackboard.Prompt:Below is a chi-square and Cramer’s V statistic from Maricopa County’s Sheriff Offices’ Annual Report (2014-2015). The tables tests the relationship between whether a driver had an item seized by that driver’s race. The chi-square is significant, so a relationship exists. What does this tell us about the Maricopa County Sheriff's Office? How does the Cramer’s V weigh in here? In other words, according to this data, does MCSO discriminate based on race? If so, which races and how much does race account for seizures?Driver post-stop perceived race or ethnicity WhiteUnknownNative AmericanHispanicBlackAsianTotalDriver item seized - No187472714015671198856927647Driver item seized - Yes268223131475476Total190152734245802203557428123Chi-Square64.29** Cramer's V0.048** + p < 0.10; * p <0.05; ** p < 0.01

Questions:
For each investment class in Table 3, assume that future returns are normally distributed with the population mean and standard deviation as given. Answer the next 5 questions
Tutorial video for excel formula: https://www.viddler.com/embed/ebd96754
Based on this assumption:
1)For each investment class, find the probability of a return that is less than zero (that is, find the probability of a loss). Is your answer reasonable for all investment classes? Explain.
2)For each investment class, find the probability of a return that is:
Greater than 5%.
Greater than 10%.
Greater than 20%.
Greater than 50%.
Fixed Annuities
Cash Equivalents
US Treasury Bonds
US Investment-grade Corporate Bonds
Non US Corporate Bonds
Domestic Large Cap Stocks
International Equities
Domestic Mid Cap Stocks
Domestic Small Cap Stocks
P(x>5%)
P(x>10%)
P(x>20%)
P(x>50%)
3)For which investment classes is the probability of the return greater than 50% is essentially zero? For which investment classes is the probability of such a return greater than 1 percent? Greater than 5%?
4)For which investment classes is the probability of loss essentially zero?
5)For which investment classes is the probability of loss greater than 1%? Greater than 10%? Greater than 20%?
