Tests of Hypotheses math statistics

A mixture of pulverized fuel ash and Portland cement to be used for grouting should have a compressive strength of more than 1300 KN/m2. The mixture will not be used unless experimental evidence indicates conclusively that the strength specification has been met. Suppose compressive strength for specimens of this mixture is normally distributed with σ = 56. Let μ denote the true average compressive strength B)Let X denote the sample average compressive strength for n = 12 randomly selected specimens. Consider the test procedure with test statistic X and rejection region x ≥ 1331.26. mean of the test statistic KN/m2 standard deviation of the test statistic KN/m2 Using the test procedure of part (b), what is the probability that the mixture will be judged unsatisfactory when in fact μ = 1350 (a type II error)? (Round your answer to four decimal places.) C) What is the probability distribution of the test statistic when μ = 1350? mean of the test statistic KN/m2 standard deviation of the test statistic KN/m2 Using the test procedure of part (b), what is the probability that the mixture will be judged unsatisfactory when in fact μ = 1350 (a type II error)? (Round your answer to four decimal places.) (d) How would you change the test procedure of part (b) to obtain a test with significance level 0.05? (Round your answer to two decimal places.) Replace 1331.26 KN/m2 with KN/m2. What impact would this change have on the error probability of part (c)? (Round your answer to four decimal places.)

(Round your answer to two decimal places.) z ≥ A new design for the braking system on a certain type of car has been proposed. For the current system, the true average braking distance at 40 mph under specified conditions is known to be 120 ft. It is proposed that the new design be implemented only if sample data strongly indicates a reduction in true average braking distance for the new design. (c) What is the significance level for the appropriate region of part (b)? (Round your answer to four decimal places.) How would you change the region to obtain a test with α = 0.001? (Round your answer to one decimal place.) Replace the limit(s) in the region with . (d) What is the probability that the new design is not implemented when its true average braking distance is actually 115 ft and the appropriate region from part (b) is used? (Round your answer to four decimal places.) (e) Let Z = (X − 120)/(σ/ n ). What is the significance level for the rejection region {z: z ≤ −2.39}? For the region {z: z ≤ −2.69} (Round your answers to four decimal places.) for {z: z ≤ −2.39 for {z: z ≤ −2.69} Let the test statistic Z have a standard normal distribution when H0 is true.

(Round your answer to four decimal places.) If it is really the case that 15% of all plates blister under these circumstances and a sample size 200 is used, how likely is it that the null hypothesis of part (a) will not be rejected by the 0.05 test?

Community Assessment and Analysis Presentation

The RN to BSN program at Grand Canyon University meets the requirements for clinical competencies as defined by the Commission on Collegiate Nursing Education (CCNE) and the American Association of Colleges of Nursing (AACN), using nontraditional experiences for practicing nurses. These experiences come in the form of direct and indirect care experiences in which licensed nursing students engage in learning within the context of their hospital organization, specific care discipline, and local communities.

This assignment consists of both an interview and a PowerPoint (PPT) presentation.

Assessment/Interview

Select a community of interest in your region. Perform a physical assessment of the community.

  1. Perform a direct assessment of a community of interest using the “Functional Health Patterns Community Assessment Guide.”
  2. Interview a community health and public health provider regarding that person’s role and experiences within the community.

Interview Guidelines

Interviews can take place in-person, by phone, or by Skype.

Develop interview questions to gather information about the role of the provider in the community and the healthissues faced by the chosen community.

Complete the “Provider Interview Acknowledgement Form” prior to conducting the interview. Submit this document separately in its respective drop box.

Compile key findings from the interview, including the interview questions used, and submit these with the presentation.

PowerPoint Presentation

Create a PowerPoint presentation of 15-20 slides (slide count does not include title and references slide) describing the chosen community interest.

Include the following in your presentation:

  1. Description of community and community boundaries: the people and the geographic, geopolitical, financial, educational level; ethnic and phenomenological features of the community, as well as types of social interactions; common goals and interests; and barriers, and challenges, including any identified social determinates of health.
  2. Summary of community assessment: (a) funding sources and (b) partnerships.
  3. Summary of interview with community health/public health provider.
  4. Identification of an issue that is lacking or an opportunity for health promotion.
  5. A conclusion summarizing your key findings and a discussion of your impressions of the general health of the community.

While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA format ting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

How has this program changed you as an individual and as a professional?
How can you highlight the skills you have demonstrated with your current employer or with a potential employer?
What can you do to remain aware of current best practices in your area of interest or expertise?

Required Resources

Use the completed assessments in this course as supporting evidence for your portfolio.
Your Professional Development Portfolio is the final portion of your capstone project. For Part I, compile specific artifacts that would be suitable to present at a job interview or performance review. In addition to the four previous assessments you have completed in this course, prepare a written summary (Part II) of your proficiency in all of the program outcomes and highlight accomplishments from your portfolio that illustrate your level of competence.

Note: You will not be re-evaluated on the four previous assessments you submit as artifacts for your Portfolio; you will only be evaluated on your written summary. Be sure, however, that you submit your entire portfolio.
Part I

Prepare your Professional Development Portfolio by compiling into a .zip file all the assessments (artifacts) you have completed for this course. Organize your portfolio in a manner that makes sense for you. To make it easier to reference specific assessments, use a numbering or lettering system such as A, B, C, and so on.

For example:

Assessment A: Health Assessment and Communication.
Assessment B: Health Promotion and Disease Prevention.

For example, in the summary you write in Part II, you would reference portions of Assessment A to support your proficiency in the corresponding competencies.
Part II

Complete the following:
