Purpose
The purpose of this project is to assess your ability to:
Collect and display data.
Use Excel.
Calculate and interpret expected value.
Calculate the mean, media, and mode of data sets.
Determine whether data sets are normally distributed.
Apply the Central Limit Theorem.
Summarize and report findings.
Overview
This module you will turn in the third part of Project 2. This project consists of three parts.
Project 2-1: Identify the Distribution of a Sample – due in Module 9
Project 2-2: Find A Sampling Distribution of Sample Means – due in Module 10
Project 2-3: Final Submission – due in Module 11
Data that follows a normal distribution pattern is predictable and can be used to draw conclusions. However, many data sets do not follow a normal distribution pattern, and a small sample may not follow the normal distribution even if it comes from a normally distributed population. The Central Limit Theorem tells us that the distribution of sample means will not only be normally distributed, but also, if we have enough samples, the sampling distribution will have a mean that is approximately the same as 𝜇, and a standard deviation that is close to 𝜎𝑛.
To see this, let’s continue the experiment using sets of randomly generated integers.
Action Items
Open your saved Excel file as submitted for Part 2.
Review your gradebook feedback and make any required corrections to Parts 1 or 2.
Complete the tab labeled “Part 3 – Calculate” by using Excel formulas to do the following:Calculate the mean and standard deviation for each of the 4 data sets from Parts 1 and 2.
Calculate the expected standard deviation of the sampling distribution of the sample means.Note, you may either calculate these directly on this tab using cell references, or calculate these using formulas on your original sheets and copy/paste the values into the designated area of the calculation sheet.
Explain how your graphs tables and calculations of the mean and standard deviations relate to the Central Limit Theorem.

This is a Maths Exploration. There is a stict guideline which we have to follow (see below). We choose our own research question, which in my case is: “Mathematically determining the ratios of musical inetrvals in different tuning systems and their levels of dissonance and consonance.” Since there is a personal background part, I have already written that part. I have my started draft as .docx file, as well as the guidelines, some background research and an example of what the paper should look like.

Hello the test is through Pearson I will provide the login once I hire you. It is 10 questions and once you enter the test you can exit it or else it will fail me. The class is a math 146 college class. I need urgent help please my sister passed away any I can get to my homework right now so I am running out of choices Thankyou.

Consider the following scenario. For a weekly pay period, you know the following information about the payroll at Fort Kent Industries.
Friday is a mandatory holiday.
 Chris receives an annual salary of $89,760.00 based on a 36-hour workweek comprised of four, nine-hour days. She has two hours of
overtime at time-and-a-half and did not work the mandatory holiday.
 Lawrence is paid $35.50 per hour based on eight-hour days and a 40-hour workweek. All premium wages are paid at regulatory
minimums. From Sunday to Saturday, he worked 8, 0, 8, 8, 8, 3, and 8 hours, respectively. He will not receive another day off in lieu
for the mandatory holiday.
 Greg receives a graduated commission of 2.25% on his first $100,000 in sales and 4.15% on anything higher. His sales during one
week were $123,000. Ignore his holiday or mandatory earnings in your calculations.
 Gunnar is paid a straight piecework wage of $2.24 per unit produced. He worked a total of 30 hours during the week, producing one
unit every five minutes. Ignore his holiday or mandatory earnings in your calculations.
 The Maine state tax rate for all employees in this scenario is 5.8%.
 Social Security tax rate is 6.2% for the employee, and 6.2% for the employer.
 The Medicare tax rate us 1.45% for the employee, and 1.45% for the employer.
 The Federal tax rate for all employees in this scenario is 22%.

Click the link below for Lab 5, and complete it on a separate sheet of paper. You do not need to copy the questions. The answers will suffice. When you have finished, click the”Submit Assignment” button. You will be given two options for submitting the Lab.
You can submit a photo, such as a cell phone photo, scan or any other type of photo. You can also simply type your responses into the submission box.
The second option will become more difficult as we begin working with charts and graphs, so a photo will be a lot easier.
