Statistics Project Essay

* My calculated test statistic of -2.07 falls in the rejection region of z < -0.1645, therefore, I would reject the null hypothesis and say there is sufficient evidence to indicate u<50 or $50,000. b. The true population proportion of customers who live in an urban area

Math 533 Project Part B In regards to the dataset from AJ Department store, your manager has speculated the following: the average (mean) annual income is less than $50,000, the true population proportion of customers who live in an urban area exceeds 40%, the average (mean) number of years lived in the current home is less than 13 years, the average (mean) credit balance for suburban customers is more than $4300. Part 1. Using the sample data, perform

I am the Statistical Analyst for Slivers’ Gold Gym (SGG). I was assigned a project to examine the relation of 252 male gym members weight and body fat by conducting a hypothesis test. This report reflects the measures that I examined and how I conducted my hypothesis test to conclude if the male members have an average body fat of 20% as claimed by my boss. Part I I analyzed the compiled sample data set that was provided to me for the hypothesis test of the body fat and weight of 252 male members

produced within a country in one year, divided by the size of the population of that country. The main objective of the present project is to establish the existence of a statistical relation between Life Expectancy (y) at birth and GDP per capita (x). First, we will present in Section 2 the data, from an official governmental source, containing Life

is to gain a better understanding of patients that are more prone to particular types of heart failure. The results could have far-reaching implications, as hypertension is a risk factor associated with many adverse cardiovascular outcomes. This project used the data from the Salerno study, and attempted to analyze and explore the variance between the three groups listed above, focusing specifically on the left ventricular end-diastolic volume variable (LVEDV). This variable measures the largest

production process at the Motive Power Company until they are totally proved over time and then can be relied upon for their rivets for larger orders. Appendix: As the data was downloaded from CANVAS class file, it is not attached. If this project involved collecting data, it would have been attached in this appendix. Please also note the following information as it appears in your syllabus to help you do cases in this class: On page 5 it says: Case Analysis: Case analysis is essential

t-Test Project MA 211 Statistics with Aviation Applications Dr. Richard Kuseski Introduction Research question: Is there a significant difference between the average age of the American Airlines fleet and the Southwest Airlines fleet of aircraft? As a legacy carrier in existence since 1930, it might be expected that American Airlines has an older fleet of aircraft than the younger Southwest Airlines. American Airlines has a large variety of aircraft models, has acquired airplanes from other legacy

For our Honors Math fall final this year we were assigned a task to collect 100 pieces of data from a survey question of our choice. With that question we surveyed 100 students from the same population. After collecting the responses we input the data into a spreadsheet to find the frequencies for each answer given. With those frequencies we then found the mean, median, mode, range, quartile 1, quartile 2, quartile 3, the interquartile range, maximum, minimum, outliers, standard deviation, and a

The total population of this study was 140 and according to Slovene’s formula, the sample size of this study was 103.In Slovene’s formula, n= N/1+N*(e) where: n= number of samples, N=total population and e = margin of error, 5%=0.05 and Population is 140 Where N=Total population=140 n=Number of samples
