Hypothesis Testing, math homework help
This is a discussion question for MAT300 (Statistics)Hypothesis testing is a pivotal concept in statistics. Hypothesis test is most commonly used when one is attempting to decide the likelihood of something being true within a population or group. Though there is a variance in the ways in which hypothesis testing can be applied ranging from medical studies to advertisements, the steps involved in the process remain constant.After reviewing the readings for this week, describe a situation in which you thought about the value of a measurement and stated a conclusion about the likelihood of that that being true (i.e. Does Dominos pizza really deliver a pizza in 30 minutes or less?). Here’s a link to for additional information on Domino’s Pizza’s 30 minute delivery promise http://www.dominos.co.in/hot-pizza-30-minutes-delivery-guarantee-at-dominos-get-pizza-hot. After your question has been scoped, outline how you would use the steps of hypothesis testing to answer your question?

Topic 1 – Descriptive Statistics Project Directions: Use the following information to complete the questions below. While APA format is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center. A researcher was interested in the anxiety present in students just prior to the midterm exam. The researcher used an anxiety self-quiz to gauge the student’s anxiety. The score for 30 students are given here. 69 99 91 66 70 98 70 53 40 58 61 66 94 77 70 56 88 85 86 40 84 86 54 48 86 43 78 53 79 89 Construct a frequency table with class, frequency, relative percent, and cumulative percent that has 6 classes to describe the distribution of the data in SPSS. Use the frequency table to construct a histogram in SPSS. Use SPSS to calculate the numerical descriptive statistics mean, median, standard deviation, and variance of the anxiety scores.

Walden Week 5 Manufacturer MPG Claim Hypothesis Testing Paper & Excel Sheet
Companies often develop and test hypotheses about their products. For example, car manufacturers will test their cars to determine fuel efficiency and miles per gallon. To ensure that products are safe and that they perform as advertised, regulatory and consumer protection groups also test companies’ claims.For this Assignment, you are working at a firm that conducts independent testing for heavy industry. Recently, an automobile manufacturer has been in the news for complaints about the highway gas mileage of their latest model minivan. You receive a contract from a consumer action group to test and write a report on the company’s claim that its minivans get 28 miles per gallon on the highway. The car company agrees to allow you to select randomly 35 low-mileage fleet minivans to test their highway mileage. Your test results gave you the following data: 29.7 24.5 27.1 29.8 29.2 27.0 27.8 24.1 29.3 25.9 26.2 24.5 32.8 26.8 27.8 24.0 23.6 29.2 26.5 27.7 27.1 23.7 24.1 27.2 25.9 26.7 27.8 27.3 27.6 22.8 25.3 26.6 26.4 27.1 26.1Submit Part 2 of your report (including the Conclusion) according to the following prompts.Part 2: Hypothesis Testing: Two-Tail Test and One-Tail Test Complete the following and include your results and responses in your report (use alpha = 0.05):List the null and alternative hypotheses for the two-tail test for the mean. Calculate the observed value of the test statistic and the associated p-value. (75–150 words, or 1–2 paragraphs) Is the observed test statistic in the critical region? Is the p-value higher or lower than your alpha? (75–150 words, or 1–2 paragraphs) Note: Include your calculations. If your calculations are submitted separately, make note of where they can be found.List the null and alternative hypotheses for the one-tail test of the mean. Calculate the observed value of the test statistic and the associated p-value. (75–150 words, or 1–2 paragraphs)Is the observed test statistic in the critical region? Will the p-value be higher or lower than your alpha? (75–150 words, or 1–2 paragraphs)Note: Include your calculations. If your calculations are submitted separately, make note of where they can be found.ConclusionsIn your report, use the confidence interval information and the results of the hypothesis testing to provide support for your conclusions and recommendations to the company. Specifically: What conclusions did you reach? What did you learn about the situation by using each method? Did one method offer more conclusive proof than another? (150–225 words, or 2–3 paragraphs)Based on your results, do you support the company’s claim that their minivans get 28 miles per gallon? (75 words, or 1 paragraph)Summarize the details of your test methods and the results from each statistical method you used. Explain the findings so that executives from both the agency and the company can understand your conclusion. (150–225 words, or 2–3 paragraphs)Finally, present recommendations for actions that the company might take to use your findings to better serve their customers in the future. (75 words, or 1 paragraph)Note: If applicable, include any files that show your calculations. Make sure that the file naming matches what you have referenced in the report.Note: For each prompt, be sure to reference at least one scholarly source to support your answer.Part 1 is att

Glendale Community College T Test Practicing Statistical Analysis
Part 1Can a student mentor improve the grades of freshman high school students? Complete parts A-D. You want to determine if pairing an incoming freshman with a sophomore in a mentor–mentee relationship will enhance the freshman’s overall grade. You recruit sophomores who are willing to mentor students in their majors for their first terms. You then recruit freshmen who are interested in having mentors. Freshmen who apply to this program will be assigned to the mentor group (and will be given mentors) or to the control group (no mentor) on an alternating basis. Those in the mentor group are to meet their mentors in person once a week at a time of their choosing. All freshmen, in both groups, agree to submit their transcripts at the conclusion of the term.CodebookVariable: groupDefinition: Mentor group assignmentType: Categorical (1 = No mentor, 2 = In-person mentor)Variable: gradeDefinition: Student’s overall gradeType: Continuous (0–100)A.Write the hypotheses.B. Run each criterion of the pretest checklist (normality, homogeneity of variance, and n) and discuss your findings.C.Run the t test and document your findings (ns, means, and significance [p value]).D.Write an abstract up to 200 words detailing a summary of the study, the t test results, hypothesis resolution, and implications of your findings.Part 2Are men and women of significantly different ages when they become parents?From the General Social Survey (GSS) 2018 database (https://gssdataexplorer.norc.org/ (Links to an external site.)), you will analyze the results of a t-test with the variables sex and agekdbrn applied to the model.You must refer to the following SPSS output information provided here, if you are to complete both parts of the assignment, Chapter 5 Practice Exercises Data Output Report.htmWrite the hypothesesAssess each criterion of the pretest checklist (normality, homogeneity of variance, and n). Interpret the outcome. In up to 200 words, write a detailed summary and interpretation of the t test results, state your hypothesis resolution, and discuss the implications of the findings. -To receive full credit for this assignment, you must submit a written abstract that contains your full written analysis/interpretation of the data as per both outcomes of each t-test.
