Make a table of values that includes the vertex.c. Use the information to graph the function. 1. f(x) = ­3x^2 + 8x2. f(x) = 2x^2 + 7x + 1Determine whether each function has a maximum or minimum value. State the maximum or minimum value of each function.3. f(x) = x^2 + 6x + 94. f(x) = ­x^2 + 4x5. Write a quadratic equation with roots ­3 and 4 in standard form.Solve each quadratic equation using the method of your choice.

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. Deliverables The deliverable is a Word document with your answers to the questions posed below based on the article you find. Required Software Microsoft Word Internet access to read articles Steps to Complete the Week 7 Lab Step 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 spreadsheet Step 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. Grading This activity will be graded based on the Week 7 Lab Rubric.
