Required ResourcesRead/review the following resources for this activity:OpenStax Textbook: Chapter 8LessonChamberlain University LibraryScenario/SummaryThe highlight of this week's lab is confidence intervals and the use of these intervals in the health sciences. There is a short reading that specifically relates confidence intervals to health sciences and then you are asked to demonstrate your knowledge of confidence intervals by applying them in a practical manner.DeliverablesThe deliverable is a Word document with your answers to the questions posed below based on the article you find.Required SoftwareMicrosoft WordInternet access to read articlesSteps to Complete the Week 7 LabStep 1: Find these articles in the Chamberlain Library. Once you click each link, you will be logged into the Library and then click on "PDF Full Text".First Article: Confidence Intervals, Part 1 (Links to an external site.) (Links to an external site.)Links to an external site. (Links to an external site.)Second Article: Confidence Intervals, Part 2 (Links to an external site.) (Links to an external site.)Links to an external site. (Links to an external site.)Step 2: Consider the use of confidence intervals in health sciences with these articles as inspiration and insights.Step 3: Using the data you collected for the Week 5 Lab (heights of 10 different people that you work with), discuss your method of collection for the values that you are using in your study. What are some faults with this type of data collection? What other type of data collection could you have used, and how might this have affected your study?Step 4: Now use the Week 6 Spreadsheet (Links to an external site.) to help you with calculations for the following questions/statements.Give a point estimate for the average height of all people at the place where you work. Start by putting the ten heights you are working with into the blue Data column of the spreadsheet. What is your point estimate, and what does this mean?Find a 95% confidence interval for the true mean height of all the people at your place of work. What is the interval?Give a practical interpretation of the interval you found in part b, and explain carefully what the output means. (For example, you might say, "I am 95% confident that the true mean height of all of the people in my company is between 64 inches and 68 inches").Post a screenshot of your work from the t value Confidence Interval for µ from the Confidence Interval tab on the Week 6 Excel spreadsheetStep 5: Now, find a 99% confidence interval for the same data. Would the margin of error be larger or smaller for the 99% CI? Explain your reasoning.Step 6: Save the Week 7 Lab document with your answers and include your name in the title.Step 7: Submit the document.GradingThis activity will be graded based on the Week 7 Lab Rubric.Course Outcomes (CO): 8RubricWeek 7 Assignment: LabCriteriaRatingsPtsThis criterion is linked to a Learning OutcomeData Collection and Pitfalls Range12.0 ptsProficient Lab includes all of the following: *10 data points/heights *method of collection *faults with method of collection used *a different method of collection10.2 ptsAbove Average Lab includes 3 out of 4 of the following: *10 data points/heights *method of collection *faults with method of collection used *a different method of collection8.4 ptsAverage Lab includes 2 out of 4 of the following: *10 data points/heights *method of collection *faults with method of collection used *a different method of collection6.6 ptsNeeds Improvement Lab includes 1 out of 4 of the following: *10 data points/heights *method of collection *faults with method of collection used *a different method of collection0.0 ptsNo Effort12.0 ptsThis criterion is linked to a Learning OutcomeEstimate a Confidence Interval15.0 ptsProficient Lab includes all of the following: *point estimate *95% confidence interval *screenshot of Excel spreadsheet *practical interpretation on confidence interval12.75 ptsAbove Average Lab includes 3 out of 4 of the following: *point estimate *95% confidence interval *screenshot of Excel spreadsheet *practical interpretation on confidence interval10.5 ptsAverage Lab includes 2 out of 4 of the following: *point estimate *95% confidence interval *screenshot of Excel spreadsheet *practical interpretation on confidence interval8.25 ptsNeeds Improvement Lab includes 1 out of 4 of the following: *point estimate *95% confidence interval *screenshot of Excel spreadsheet *practical interpretation on confidence interval0.0 ptsNo Effort15.0 ptsThis criterion is linked to a Learning OutcomeInterpret a Confidence Interval15.0 ptsProficient Lab addresses all of the following well *a 99% confidence interval *comparison of margins of error for 99% and 95% *explanation of reasoning12.75 ptsAbove Average Lab addresses 2 out of 3 of the following well *a 99% confidence interval *comparison of margins of error for 99% and 95% *explanation of reasoning10.5 ptsAverage Lab addresses 1 out of 3 of the following well *a 99% confidence interval *comparison of margins of error for 99% and 95% *explanation of reasoning8.25 ptsNeeds Improvement Lab mentions but does not explain fully any of the following *a 99% confidence interval *comparison of margins of error for 99% and 95% *explanation of reasoning0.0 ptsNo Effort15.0 ptsThis criterion is linked to a Learning OutcomeGrammar and Formatting8.0 ptsProficient Lab is easy to read and presents material in a logical order with no grammatical errors.6.8 ptsAbove Average Lab is easy to read and presents material in a logical order.

National polls are often conducted by asking the opinions of a few thousand adults nationwide and using them to infer the opinions of all adults in the nation. Explain who is in the sample and who is in the population for such polls. Please use a poll from a newspaper, TV, a magazine, or from the Internet (Chapter 8).You may use the information in the textbook or cite a source. FYI : Chapter 8 - Hypothesis Testing: All Sections Elementary Statistics, 13th Edition
