I’m trying to learn for my Statistics class and I’m stuck. Can you help?

The detailed assignment requirement is post in the attached file, please check, this is a statistic project.

Instructions:

1. (5 points) Choose a population and a quantitative variable. Clearly state your choices in a few sentences.

2. (5 points) Choose a significance level α. Justify your choice in one to two sentences.

3. (20 points) Choose the appropriate hypothesis test for the population mean. Justify your choice by carefully checking the conditions.

4. (10 points) Collect a simple random sample of 10−50 individuals from your population. Give a detailed description of your sampling method and justify why it is a simple random sampling method in one to two paragraphs. Justify your choice of sample size in one paragraph.

5. (10 points) Choose a null hypothesis. Explain your choice in one to two sentences.

6. (10 points) Compute the test statistic. Your work should include your sample data, the sample size, sample mean, and the equations or functions you used.

7. (10 points) Estimate the p-values for each alternative hypothesis. Briefly explain your work.

8. (10 points) Compare each of your p-values to your chosen significance level. Write the appropriate conclusion sentences for each comparison.

9. (10 points) Construct the appropriate confidence interval from your sample data using a confidence level which is C = 1 − α 2 . Does your confidence interval contain the claimed value of the population mean from the null hypothesis?

10. (10 points) What do your hypothesis test results and confidence interval tell you about the population mean for your variable? Justify your answer in one to two paragraphsRespond these 5 writing questions: assignment help online

Instructions

Assignments must be completed on MindTap AND a completed workbook with your full completed solutions must be submitted via Sakai. You must submit both in order to receive any credit.

Hardcopies or copies emailed will not be graded.

There is no option for late submissions in MindTap. Failure to submit your submit your assignment on MindTap before the due date will result in zero credit.

Submit your worked data in one single MS Excel Workbook. Start your solution set by using the assignment shell provided on Sakai. Use appropriately labeled worksheets for each problem/section of a problem.

Pay very close attention to the final presentation of your work and make sure it is print-ready. Prepare all spreadsheets so that they are clear, attractive and easy for the untrained eye to follow and understand. While accurate content and precise execution of the techniques is critical, formatting, typographical and grammatical acuteness is also very important. General sloppiness and inconsistent formatting will lower your grade.

Note: Ignore MindTap warning about text-based answers. All open ended questions will be graded as well. In fact, your grade will depend equally on the accuracy of your analytical techniques and your interpretation of the results.

Assignment files should be named as follows:

Question 1. 50 points

In PC Tech’s product mix problem that we solved this week, assume there is another PC model, the VXP, that the company can produce in addition to Basics and XPs.

The following inputs are available:
The most it can sell are 600 Basics, 1200 XPs, and 50 VXPs Each Basic sells for $300 , each XP for $450, each VXP sells for $560 The cost of component parts for a Basic is $150; for an XP is $225; for a VXP is $275 There are at most 10,000 assembly hours and 3000 testing hours available. Each Basic requires five hours for assembling and one hour for testing,; each XP requires six hours for assembling and two hours for testing; each VXP requires eight hours for assembling and three hours for testing Each labor hour for assembling costs $11 and for testing costs $15.
From these available inputs, calculate the following inputs:
Unit Margins = (Selling Price) – (Labor hours for assembly) * (Cost per labor hour assembling) – (Labor hours for testing) * (Cost per labor hour testing) – (Cost of component parts) Labor used = (Labor hours) * (Number to produce) Profit = (Unit margin) * (Number to produce) Total profit = (Net profit for Basic) + (Net profit for XP) + (Net profit for VXP)
A.Use an LP spreadsheet model to find the best mix of computer models that stays within the company’s labor availability and maximum sales constraints and maximizes total profit.What is the optimal product mix? How many computers of each model should PC Tech produce?

B.You should find that the optimal solution is not integer-valued. If you round the values in the decision variable cells to the nearest integers, is the resulting solution still feasible?(Note: You must manually round off the cell values. Simply changing the display of decimal points will not alter the cell value.)If the resulting solution is no longer feasible, how might you obtain a feasible solution that is at least close to optimal?

Question 2. 50 points

A furniture company manufactures desks and chairs.
Each desk uses four units of wood, and each chair uses three units of wood. A desk contributes $400 to profit, and a chair contributes $250. Marketing restrictions require that the number of chairs produced be at least twice the number of desks produced. There are 2000 units of wood available. Calculate Profit = (Unit margin) * (Units produced) for all furniture.
A.Use Solver to maximize the company’s profit. How many desks and chairs should the furniture company produce?

DO NOT Answer Parts B and C of Question 2.Which problem would best be solved using bevelled 22 over 7 as an approximation of ​π​?

I don’t know how to handle this Calculus question and need guidance.

At the end of each semester, we survey students who used WeBWorK. On the whole, students have found using WeBWorK to be helpful, but there are some problems/complaints which come up. Here we present the most common problems and advice on how to avoid them.

In most cases, problems can be avoided by doing three things:
Start working on your homework early; you can then fix problems before an assignment is due. Use the Preview button to see how WeBWorK has parsed your answer. When you are having trouble, get help from a person (your teacher, a tutor, or a classmate).
The third suggestion is probably the most important. WeBWorK will show you which problems you are having difficulty with. It is then up to you to get help with them. If you have started early, you can still get the problems right.
