The purpose of this discussion is to allow you to consider how nonparametric tests are used and how two types of chi-square tests compare. To do this, you will need to explain statistical concepts and assess assumptions, limitations, and implications associated with statistical tests. For your initial post, Describe the chi-square goodness-of-fit test. Explain what this test measures. Explain how the chi-square goodness-of-fit test is […]
This week focuses on applications of measurement. One of the basic concepts of geometry is learning to calculate the perimeter and area of two-dimensional shapes. Once that is mastered, you can calculate surface area and volume for three-dimensional shapes. Respond to the following in a minimum of 175 words: Research the flag for the state in which you live and share a picture of the […]

Type your responses in a Word (or Excel where applicable) document. Be sure to number your responses properly. Show all your calculations where applicable.
Initial Post Instructions Topic: Poisson Probability Distribution The Poisson Distribution is a discrete probability distribution where the number of occurrences in one interval (time or area) is independent of the number of occurrences in other intervals. April Showers bring May Flowers!! Research the “Average Amount of Days of Precipitation in April” for a city of your choice. In your initial post, Introduce Introduce the City […]
A bird species in danger of extinction has a population that is decreasing exponentially (A = A0e^kt). Five years ago, the population was at 1400 and today only 1000 of the birds are alive. Once the population drops below 100, he situation will be irreversible. When will this happen? According to the U. S. Bureau of the Census, in 2000 there were 35.3 million residents […]
Solve each logarithmic equation. Be sure to reject any value of x that is not in the domain of the original logarithmic expressions. Give the exact answer. Then, use a calculator to obtain a decimal approximation to three decimal places, for the solution. log2 (x_3) + log2 x _ log2 (x+2) =2 ln (x_4) + ln (x+1) = ln (x _8) 2 log3 (x+4) =log3 […]
Hypotheses testing: Show your hypothesis test and discuss any conclusions they suggest State the hypotheses you will test and formally write them in proper notation Give the results (reject, fail to reject) and explain what that means in a practical way. Conclusion: Discuss the weaknesses of your study. To what population do you feel comfortable extrapolating your results? Why? Give suggestions for further work in […]
Week 4 Assignment – Case Study: Transforming Data Into Information Overview The Woodmill Company makes windows and door trim products.

Question 6 1 point In chemistry the volume for a certain gas is given by V=25TV=25T, where VV is measured in cc and TT is temperature in °C°C. If the temperature varies between 90°C90°C and 110°C110°C , find the set of volume values. Enter the exact answer in interval notation. To enter __, type infinity. To enter __, type U. Do not enter any commas in your answer. […]
The manager of a fast-food store realizes that her staffing problems are a result of the variation in the number of customers that arrive at the store. If the same number of customers came each hour, she would know exactly how many servers to have working. It turns out that the Poisson distribution works well to describe the arrivals of customers in any given hour. […]
