Very easy but has to be done well

Question 1Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01.What is the mean score of the population?What is the mean score of the sample?Is this test one-tailed or two-tailed? Why?What is the null hypothesis in this case?If p = 0.29, should Colby reject or fail to reject the null hypothesis?What should Colby’s statement of conclusion be? (This circles back to what is being tested).The next two ask you do to a hypothesis test. Remember, hypothesis tests follow a series of steps. They are not just a computer printout. Make sure if you use a computer printout, you identify which parts of the printout apply to the problem. All of the parts of the printout will NOT apply.Question 2A sample of 22 account balances of a credit company showed a mean customer balance of $4,300, but the marketing manager claimed that the mean balance for the population was $4450. The marketing manager did NOT have the population standard deviation, but the sample standard deviation was found to be $400. Use the p-value approach to conduct a full hypothesis test(all steps) that can be used to determine whether the mean of all account balances is significantly different from $4440. Let α = .05.Question 3A sample of 150 homes for sale in ABC City showed a mean asking price of $233,000, but the city claimed that the mean asking price for the population was $255,000. The population standard deviation of all homes for sale was $11,000. Use the p-value approach to conduct a full hypothesis test (all steps) that can be used to determine whether the mean asking price is significantly less than $255,000. Let α = .10.Question 4During the recent primary elections, the democratic presidential candidate showed the following pre-election voter support in Alabama and Mississippi.StateVoters Surveyed Voters in favor of Democratic CandidateAlabama710352Mississippi 915480We want to determine whether or not the PROPORTIONS of voters favoring the Democratic candidate were the same in both states. In other words, is the first proportion (p1) the same as (p2)? What formula, from this week’s Notations and Symbols, would be applicable in the hypothesis test? (Notice you are not doing a hypothesis test – you are saying which formula applies).

This is a two part assignment.Discussion:Create a comprehensive explanation of a future analysis Teton Grand could run at some point inthe future and how significance testing, confidence intervals and standard error of measurementwould help them understand the results. Your post should be in a client-ready format, usingprofessional and language appropriate for talking to an organization.The assignment should be posted as a video (must include narration) of you describing the futureanalysis for Teton Grand. Assignment:Teton Grand is interested in hiring a statistician intern for the summer to help them analyze data. Yourrole is to explain statistical concepts to the intern so that he/she has a good foundation for running theseanalyses moving forward.You must explain the purpose and use of significance testing, confidence intervals and standard error ofmeasurement using examples for how each concept could be used in relation to Teton Grand’s data.You are not expected to run any analyses this week but this exercise should highlight your ability to talkcredibly about the value of each statistical concept. You must go beyond simply defining the concepts totalking about their relevance to Teton Grand.This can be in a video format, presentation, or step-by-step handout. It must be client-ready,professionally formatted, and easy to understand. If creating a video, length should be approximately 5-10 minutes. If creating a presentation, the length should be approximately 10-15 slides. Your submissionshould adhere to the APA format and guidelines.Resources:Technical Information: This assignment may require a video submission.
