Tutoring on the Normal Distribution
CompetencyDemonstrate the use of the normal distribution, the standard normal distribution, and the central limit theorem for calculating areas under the normal curve and exploring these concepts in real life applications.ScenarioFrank has only had a brief introduction to statistics when he was in high school 12 years ago, and that did not cover inferential statistics. He is not confident in his ability to answer some of the problems posed in the course.As Frank's tutor, you need to provide Frank with guidance and instruction on a worksheet he has partially filled out. Your job is to help him understand and comprehend the material. You should not simply be providing him with an answer as this will not help when it comes time to take the test. Instead, you will be providing a step-by-step breakdown of the problems including an explanation on why you did each step and using proper terminology.What to SubmitTo complete this assignment, you must first download the word document, and then complete it by including the following items on the worksheet:Incorrect AnswersCorrect any wrong answers. You must also explain the error performed in the problem in your own words.Partially Finished WorkComplete any partially completed work. Make sure to provide step-by-step instructions including explanations.Blank QuestionsShow how to complete any blank questions by providing step-by-step instructions including explanations.Your step-by-step breakdown of the problems, including explanations, should be present within the word document provided. You must also include an Excel workbook which shows all your calculations performed.

Need calculus help with Applications of Derivatives
1.) One train travels east at 180 mph towards Christmas Town, while a second train travels south at 130 mph away from Christmas Town. At time t = 0, the first train is 50 miles west and the second train is 30 miles south. Find the rate at which the distance between the trains is changing at time t = 40 minutes.2.) Water pours into a conical tank of height 7 ft and radius 4 ft at a rate of 1.3 ft3/min. How fast is the water level rising when it is 4 ft high?3.) Farmer Kenny has a fence of length 22 ft. Kenny wants to create the biggest grazing area possible. What is the maximal area of the grazing area?4.) A box is constructed out of two different materials. The material for the top and bottom (both square pieces) cost $2/ft2 and the material for the sides costs $4/ft2. Find the dimensions that minimize the cost if the box has a volume of 120 ft3

Statistic using Excel spread sheet/T1-T84 calculator.
The Excel spread sheet and pdf is for Experience 2 Application only.EXPERIENCE 3 ASSISGNMENT Suppose you are representing the employees at a large corporation during contract negotiations. You have a list of the salaries of all the employees at the corporation (The salaries include the many lower level employees and the few high paid management employees) and you plan to find a measure of center (e.g. mean, median, or mode).a. Which measure or center would you use to represent the employees in an effort to support your claim that the average salary of lower level employees is much lower than the national average (for lower level employees) and thus should be increased?meanmodemedianb. Why is this the better choice?Suppose you wish to invest money safely and are trying to decide between stock options in two companies. The average rates of return are the same for both companies but, one company has a much larger standard deviation of its rates of return. a. Which company should you invest in?The company with the smaller standard deviationThe company with the larger standard deviationb. Why is this the better choice? Describe the shape of the distribution for the following and justify your answer:a. The distance people travel to work on a typical day - The horizontal axis is the distance traveled in a person's daily commute. The vertical axis is frequency (number of people with that distance for their daily commute). Shape of distribution:skewed leftuniformskewed rightsymmetricJustification:b. Number of hours of sleep for each night of the week (weekdays only) - The horizontal axis is the day of the week (Monday to Friday) and the vertical axis is the amount of sleep in hours for that night. Shape of distribution:symmetricuniformskewed leftskewed rightJustification:c. Age of first heart attack - The horizontal axis is age. The vertical axis is frequency (number of people who had their first heart attack at that age). The population is people in the US who have had at least one heart attack. Shape of distribution:uniformsymmetricskewed leftskewed rightJustification:d. Scores on the Graduate Requirement Exam - This is a standardized test for people entering graduate school. The horizontal axis would be the person's total score. The vertical axis would be frequency (number of people with that score). The population would be all GRE test takers for a given year. Shape of distribution:symmetricskewed rightuniformskewed leftJustification:EXPERIENCE 2 APPLICATIONYou must use spreadsheet software (e.g. Excel) for this problem. 1. For each state and Washington DC, the percentage of people without health insurance was determined. Given the data set (The file is located in the main Experience folder) create the following using spreadsheet software. Refer to the model/methodology for the desired format. Make sure to use 5-20 classes with a "nice" class width when creating the distribution tables. Make sure to label axes in both graphs. a. Grouped frequency distribution (table) b. Grouped relative frequency distribution (table) c. frequency histogram (graph) d. relative frequency histogram (graph) Submit the completed spreadsheet as a .xls or .xlsx file. 2. A survey of 50 college students was conducted to determine how much weekly income they earned from employment. Given the data set in Applications folder for this experience complete the following. Refer to the model/methodology for the desired format. a. Find the 5 number summary of the data set. Min= Q1= Median= Q3= Max= b. Create a box-plot for the data set using software (Choices include: The boxplot generator linked in the resources area, spreadsheet software, TI-84 (take a picture of your calculator), other software or websites.) Upload your finished file below. Question 2 Part 6 of 9Choose File No file chosen c. Identify any outliers. List the individual numbers that are outliers for this data set. If there are multiple outliers, separate them by commas. d. Give a possible explanation as to why the individual (or individuals) from part c might have a number (or numbers) that are so high (or so low). e. Interpret yourself as a percentile in the data set. First estimate your weekly income from employment (If you are not employed then use 0). Then find the percentile (see book for the formula) for your income using the sample data. Then interpret the percentile using the definition and writing a complete sentence.

Algebra Distributive Property Worksheet
Explain the distributive, inverse, and identity properties in simple language with no formalities.
Select two examples for each property.
Explain how each example fits each property.
2. Create your own linear scenario and problem. Have at least two parts to your problem for your classmates to solve. Make sure you know the answer to your own problem!
Here is an example of a linear scenario and problem: A new car costs $21,000, and the car’s value depreciates linearly to $10,500 in three years. Explain the process to write a formula that expresses the car’s value, V, in terms of its age, t, in years. What is the car’s value in 5 years? At what point is the formula useless? Explain. (Do NOT use this example as your linear scenario and problem.)
3. Suppose that the volume of a box is (2p3 + 15p2 + 28p) cubic feet. The height is p feet and the length is (p + 4) feet. Explain the process to find an expression that represents the width. Based on answering this problem, create a new scenario for your classmates to complete.
4. Teach the class how to use the greatest common factor (GCF) to simplify a polynomial expression. Illustrate the concept with examples. Remember that teaching requires detailed explanation, as well as the actual math.
5. Teach your classmates the process to find the domain of a rational function. Illustrate the concept with two examples, one of which requires factoring. Please include both set notation and interval notation as part of your teaching. Remember that teaching requires detailed explanation, as well as the actual math.
