Description
2y - 3/4x = -10
y+1/4x=0

Explanation & Answer
Solve one of the equations for x:
y + 1/4x = 0
(I'm going to multiply the entire equation by 4 to get rid of the fraction):
4(y+1/4x = 0)
4y + x = 0
x = -4y
Now substitute x = -4y into the first equation:
2y - 3/4x = -10
2y - 3/4(4y) = -10
2y - 3y = -10
-y = -10
y = 10
Substitute y = 10 into the first equation. Again, I'm going to use the equation multiplied by 4 because it's easier:
4y + x = 0
4(10) + x = 0
40 + x = 0
x = -40

Week 8 Statistical Testing in Manufacturing PPT
WEEK 8 ASSIGNMENT - CASE STUDY: STATISTICAL INFERENCEWeek 8 Assignment - Case Study: Statistical InferenceOverviewThe research department of an appliance manufacturing firm has developed a solid-state switch for its blender that the research department claims will reduce appliance returns under the one-year full warranty by 3%6%. To determine if the claim can be supported, the testing department selects a group of the blenders manufactured with the new switch and a group with the old switch and subjects them to a normal years worth of wear. Out of 250 blenders tested with the new switch, nine would have been returned. Sixteen would have been returned out of the 250 blenders with the old switch. As the manager of the appliance manufacturing process, use a statistical procedure to verify or refute the research departments claim.InstructionsCreate 810 slides, including a cover and a sources list, for a presentation to the director of the manufacturing plant in which you: Summarize the problem with the appliance manufacturing firm's blenders. Propose the statistical inference to use to solve the problem. Support your decision using a scholarly reference. Using Excel:Develop a flowchart for the proposed statistical inference, including specific steps. Compute all statistical calculations using Excel. Place your flowchart in a slide.Determine if you can verify or refute the research department's claim.Choose sources that are credible, relevant, and appropriate. Cite each source listed on your source page at least one time within your assignment. For help with research, writing, and citation, access the library or review library guides.

Springdale SHopping Survey
Instructions The major shopping areas in the community of Springdale include Springdale Mall, West Mall, and the downtown area on Main Street. A telephone survey has been conducted to identify strengths and weaknesses of these areas and to find out how they fit into the shopping activities of local residents. The 150 respondents were also asked to provide information about themselves and their shopping habits. The data are provided in the file SHOPPING. The variables in the survey can be found in the file CODING.In this exercise, some of the estimation techniques presented in the module will be applied to the Springfield Shopping survey results. You may assume that these respondents represent a simple random sample of all potential respondents within the community, and that the population is large enough that application of the finite population correction would not make an appreciable difference in the results.Managers associated with shopping areas like these find it useful to have point estimates regarding variables describing the characteristics and behaviors of their customers. In addition, it is helpful for them to have some idea as to the likely accuracy of these estimates. Therein lies the benefit of the techniques presented in this module and applied here.1.Item C in the description of the data collection instrument lists variables 7, 8, and 9, which represent the respondent’s general attitude toward each of the three shopping areas. Each of these variables has numerically equal distances between the possible responses, and for purposes of analysis they may be considered to be of the interval scale of measurement.1.Determine the point estimate, and then construct the 95% confidence interval for μ7 = the average attitude toward Springdale Mall.2.Repeat part (a) for μ8 and μ9, the average attitudes toward Downtown and West Mall, respectively.2.Given the breakdown of responses for variable 26 (sex of respondent), determine the point estimate, and then construct the 95% confidence interval for p26 = the population proportion of males.3.Given the breakdown of responses for variable 28 (marital status of respondent), determine the point estimate, and then construct the 95% confidence interval for p28 = the population proportion in the “single or other” category.4.Assume the managers have requested estimates of the mean attitudes towards each mall with a margin of error of 0.05 for each. If the managers want to have 95% confidence that the sample mean will fall within this margin of error, how large should the sample size be for each mall?RequirementsMust answer questions in detailMust include Excel Worksheet that proves work!

Each swimmer is allowed to compete in 7 events at a swim meet. Danny got first place 3 times, second place 1 time, third 2 times, and fourth once. John got first 2 times, second place 3 times, third twice, and didn’t place fourth. Kenny didn’t place first, but was second once, third four times, and fourth two times. Sean placed first once, second twice, third three times, and fourth once. The club teams are waiting to see which trophy they will be getting. Their trophy is based on the amount of points each team received. Eagles Aquatics team had 8 people get first place, 9 in second, 10 in third, and 5 in fourth. The Pirates swim team had 6 people get first, 7 in second, 3 in third, and 1 in fourth. Devil Rays Aquatic Club had 9 people get first, 2 in second, 5 in third, and 7 in fourth. The Manta Rays swim team had 4 first place winners, 3 second, 2 third and 1 fourth. 1. First place receives 6 points, second 4, third 3, and fourth 2. Which swimmer got the most points? Which team won the trophy? Show how you found that out.2. Does it matter in what order you multiply the matrices? Explain.3. If you were to find out the total number of points scored by individuals and teams, how would you go about doing that?4. Look back at what you did for questions 1 and 2. How does this relate to your understanding of vectors?5. Come prepared to share another example of a problem in the real world that can be solved using matrices.
