Description
x+2y=2
2x+4y=32

Explanation & Answer
Dividing both sides of the second equation by 2 gives:
2x/2 + 4y/2 =32/2
or x + 2y = 32 (2)
but the first equation says
x + 2y = 2 (1)
So it is not possible to solve these two equations - the two lines are parallel

Stats Phase 3
Option 2 Scenario Option 2 Data SetDiscuss the process for hypothesis testing.
Explain the 8 steps of hypothesis testingWhen performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?Perform the hypothesis test. If you selected Option 1 (Salaries):
Claim: The average salary for all
jobs in Minnesota is less than $65,000. Test the claim using α = 0.05
and assume your data is normally distributed and σ is unknown.
If you selected Option 2 (Patients at NLEX hospital):
Claim: The average age of all
patients admitted to the hospital with infectious diseases is less than
65 years of age. Test the claim using α = 0.05 and assume your data
is normally distributed and σ is unknown.
Based on your selected topic, perform and document the following steps:
Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.Is the test two-tailed, left-tailed, or right-tailed? Explain.Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.What is the value of the test-statistic? Show your calculationWhat is the P-value? Explain how you determined it What is the critical value? Explain how you calculated itWhat is your decision? Reject the null or do not
reject the null? Explain why you made your decision including the
results for your p-value and the critical value.State the final conclusion in non-technical terms.
Please show your work for the construction of the test-statistic
and explain your process for finding the p-value and critical value.
You may use the Equation Editor to format your calculation steps on the
Word document or attach an Excel spreadsheet clearly showing each
calculation for #B4 and #B5, but your answers still need to appear on
the Word document. Also, be sure to number each response in your paper using the same numbers as above

STAT 2002 Walden University Testing a Manufacturers MPG Claim Homework
Note: Last week, you submitted Part 1 of this Assignment. This week, you will complete and submit only Part 2 (including the Conclusion).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 26.1To prepare for this Assignment:Refer to last week's Assignment to complete the Conclusion section of this Assignment.Submit Part 2 of your report (including the Conclusion) according to the following prompts.Part 2: Hypothesis Testing: Two-Tail Test and One-Tail TestComplete 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: For each prompt, be sure to reference at least one scholarly source to support your answer (6 prompt= 6 citations)
