About 25 statistical math questions, I will put one of the sample questions below, please make sure that this part of the content can be answered before taking the order
Unformatted Attachment Preview
Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion
about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2008 passenger cars in a
particular region, 233 had only rear license plates. Among 325 commercial trucks, 46 had only rear license plates. A
reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners
of passenger cars. Use a 0.05 significance level to test that hypothesis.
a. Test the claim using a hypothesis test.
b. Test the claim by constructing an appropriate confidence interval.
H1: P1 P2
Identify the test statistic.
- 1.31 (Round to two decimal places as needed.)
Identify the P-value.
0.095 (Round to three decimal places as needed.)
State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.
A. Reject Ho. There is sufficient evidence to support the claim that commercial trucks owners violate laws requiring front
license plates at a higher rate than owners of passenger cars.
B. Fail to reject Ho. There is not sufficient evidence to support the claim that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of passenger cars.
O C. Reject Ho. There is not sufficient evidence to support the claim that commercial trucks owners violate laws requiring
front license plates at a higher rate than owners of passenger cars.
O D. Fail to reject Ho. There is sufficient evidence to support the claim that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of passenger cars.
b. Identify the confidence interval limits for the appropriate confidence interval. Let population 1 correspond to the
passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license
plate.

Assignment: Evaluating Significance of Findings
Part of your task as a scholar-practitioner is to act as a critical consumer of research and ask informed questions of published material. Sometimes, claims are made that do not match the results of the analysis. Unfortunately, this is why statistics is sometimes unfairly associated with telling lies. These misalignments might not be solely attributable to statistical nonsense, but also “user error.” One of the greatest areas of user error is within the practice of hypothesis testing and interpreting statistical significance. As you continue to consume research, be sure and read everything with a critical eye and call out statements that do not match the results. For this Assignment, you will examine statistical significance and meaningfulness based on sample statements. Critically evaluate each of the two scenarios (See scenarios below) selected based upon the following points: Critically evaluate the sample size. Critically evaluate the statements for meaningfulness. Critically evaluate the statements for statistical significance. Based on your evaluation, provide an explanation of the implications for social change. Scenario #1 Statistical significance is found in a study, but the effect in reality is very small (i.e., there was a very minor difference in attitude between men and women). Were the results meaningful? An independent samples t test was conducted to determine whether differences exist between men and women on cultural competency scores. The samples consisted of 663 women and 650 men taken from a convenience sample of public, private, and non-profit organizations. Each participant was administered an instrument that measured his or her current levels of cultural competency. The cultural competency score ranges from 0 to 10, with higher scores indicating higher levels of cultural competency. The descriptive statistics indicate women have higher levels of cultural competency (M = 9.2, SD = 3.2) than men (M = 8.9, SD = 2.1). The results were significant t (1311) = 2.0, p <.05, indicating that women are more culturally competent than are men. These results tell us that gender-specific interventions targeted toward men may assist in bolstering cultural competency. Scenario #2 A study has results that seem fine, but there is no clear association to social change. What is missing? A correlation test was conducted to determine whether a relationship exists between level of income and job satisfaction. The sample consisted of 432 employees equally represented across public, private, and non-profit sectors. The results of the test demonstrate a strong positive correlation between the two variables, r =.87, p < .01, showing that as level of income increases, job satisfaction increases as well. Use 4 or more references with proper APA format and citations and referencing. Include the reference below. Frankfort-Nachmias, C., & Leon-Guerrero, A. (2018).

Walden University Quantitative Reasoning and Analysis Discussion
For this Discussion, you will post your response to the hypothesis test, along with the results. You will work with a real, secondary dataset to construct a research question, perform categorical data analysis that answers the question, and interpret the results. Create a research question using the General Social Survey dataset that can be answered using categorical analysis.Use SPSS to answer the research question. Post your response to the following:
What is your research question?
What is the null hypothesis for your question?
What research design would align with this question?
What dependent variable was used and how is it measured?
What independent variable is used and how is it measured?
If you found significance, what is the strength of the effect?
Explain your results for a lay audience and further explain what the answer is to your research question.
Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.Required Readings

Hypothesis Tests
CompetencyGiven a real-life application, develop a hypothesis test for a population parameter and its interpretation.InstructionsScenario (Information repeated for deliverable 01, 03, and 04)A major client of your company is interested in the salary distributions of jobs in the state of Minnesota that range from $25,000 to $200,000 per year. As a Business Analyst, your boss asks you to research and analyze the salary distributions. You are given a spreadsheet that contains the following information:A listing of the jobs by title The salary (in dollars) for each jobIn prior engagements, you have already explained to your client about the basic statistics and discussed the importance of constructing confidence intervals for the population mean. Your client says that he remembers a little bit about hypothesis testing, but he is a little fuzzy. He asks you to give him the full explanation of all steps in a hypothesis testing and wants your conclusion about a claim that the average salary for all jobs in the state of Minnesota is less than $65,000.Background information on the DataThe data set in the spreadsheet consists of 364 records that you will be analyzing from the Bureau of Labor Statistics. The data set contains a listing of several jobs titles with yearly salaries ranging from approximately $25,000 to $200,000 for the state of Minnesota.What to SubmitYour research and analysis should be presented on the Word document provided. All calculations and work should be provided on a separate Excel workbook that should be submitted to your boss as well.
