State the null hypothesis from this example in cell A35. What does the value in cell A33 tell you about the hypothesis.
One sample t Test We are now going to use Excel to test a hypothesis based on one given sample. We would like to know if the average cholesterol level of patients in intensive care is equal to 200 and for that reason we collect cholesterol level of 20 random people from various intensive care […]
Compare the t value in cell A17 to the table t value in cell A18. How does this comparison tell you if you should reject the null hypothesis or not.
Dependent groups t Test testing two mean differences CASE Use Excel to find information on correlation between two dependent groups. We would like to know if the cholesterol level depends on the age and for that reason we collect cholesterol level of 10 people, first when they were 17 and then when they are 46. […]
Using Excel, evaluate the score that corresponds to 65 percentile in standard normal distribution.
Excel program Exercise 1. Using Excel, evaluate the score that corresponds to 65 percentile in standard normal distribution. Put your result in cell A11. Exercise 2. Let X be normally distributed with mean 89 and standard deviation 15. Given P(X<a)=36% evaluate a using Excel. Put your result in cell A15.
Consider the number sets integers, rational numbers, and real numbers, then record at least 25 different numbers that you encounter in your everyday life.
Principals of math Throughout this course, you explored various mathematical topics, investigated their importance, and learned to work with them. In this culminating assignment, you will complete four (4) tasks that assess your expertise in the course material, Task 1: Principles of Mathematics Consider the number sets integers, rational numbers, and real numbers.

Describe the data in a file called Regional Call Center and produce a report that would both graphically and numerically analyze the data.
Case Study: Transforming Data Into Information Overview You are a supervisor at Regional Call Center’s Washington, DC, facility. Regional provides contract call center services for a number of companies, including banks and major retail companies. You have been with the company for slightly more than seven years, having joined Regional right after graduating with a […]
Provide an example from your current (or your future) professional or personal life that describes a measurement that is normal—and how much wiggle room on either side would be appropriate.
Confidence level Topic 1:Results from surveys or opinion polls often report a range of values—the sample statistic plus or minus a margin of error (the resulting range is called a confidence interval). This tells us that the range is likely to contain the population parameter. How much wiggle room we provide is based on how […]
Sketch S and D and determine the equilibrium set E = S n D, the supply and demand functions qS, qD, and the inverse supply and demand functions pS, pD.
Exercises 1Exercise 1.1 Ifx + y = 3 and x – 2y = -3, what are x and y ?Exercise 1.2 Solve the following simultaneous equations.2x + y = 9,x – 3y = 1. Exercise 1.3 Suppose the market for a commodity is governed by supply and demand sets defined as follows. The supply set […]
Write lecture notes about hyperbolic geometry in a vulgarized yet formal way. Include definitions of any term that was not presented in class.
Hyperbolic geometryFinal project: Write lecture notes about hyperbolic geometry in a vulgarized yet formal way. Content of the lecture notes: definitions of any term that was not presented in class (refer to the summaries of Euclidean geometry for a list of every defined term in class); examples and/or exercises with given solutions for every definition […]
