MTH 156 Colorado State University Estimator New York Survey Data MCT 6 Report
Option #2: New York Survey DataA consulting firm was hired to conduct a survey on people living in
New York City. The survey was completed monthly for six months by 445
randomly-selected people in different boroughs. There were a number of
items on the survey, but six basic biographical items will be studied
for this exercise. The data for the people surveyed in one of these
monthly surveys can be found in the Excel file SURVEY. The variables that were used for the basic biographical data are found on the last page of the exercise.In this exercise, some of the estimation techniques presented in the
module will be applied to the New York survey results. You may assume
that these respondents represent a simple random sample of all potential
respondents within the community, and that the population is large
enough that application of the finite population correction would not
make an appreciable difference in the results.New York City governmental agency personnel like to have point
estimates regarding variables describing the biographical information of
the people living within the different boroughs. It is very helpful for
them to have some idea regarding the likely accuracy of these estimates
as well. Therein lies the benefit of the techniques presented in this
module and applied here.
Item A in the description of the data collection instrument lists
variables 1 through 5, which represent the respondent’s general attitude
toward each of the five boroughs. Each of these variables has
numerically equal distances between the possible responses, and for
purposes of analysis they may be considered to be of the interval scale
of measurement.
Determine the point estimate, and then construct the 95% confidence interval for μ1= the average attitude toward Manhattan.
Repeat part (a) for μ2 through μ5, the average attitudes toward Brooklyn, Queens, The Bronx and Staten Island, respectively.
Given the breakdown of responses for variable 6 (highest level of
education), determine the point estimate, and then construct the 95%
confidence interval for p6= the population proportion of doctoral degrees.
Given the breakdown of responses for variable 7 (marital status of
respondent), determine the point estimate, and then construct the 95%
confidence interval for p7 = the population proportion in the “single or other” category.
Assume the governmental agencies requested estimates of the mean
attitudes towards each borough with a margin of error of 0.05 for each
borough. If the governmental agency personnel want to have 95%
confidence that the sample mean will fall within this margin of error,
how large should the sample sizes be for each borough?
Requirements:
Your paper should be 2-3 pages in length (not counting the title
page and references page) and cite and integrate at least one credible
outside source. The CSU Global Library is a great place to find
resources. Your textbook is a credible resource.
Include a title page, introduction, body, conclusion, and a reference page.
The introduction should describe or summarize the topic or problem.
It might discuss the general applications of the topic or it might
introduce the unique terminology associated with the topic.
The body of your paper should address the questions posed in the
problem. Explain how you approached and answered the question or solved
the problem, and, for each question, show all steps involved. Be sure
this is in paragraph format, not numbered answers like a homework
assignment.
The conclusion should summarize your thoughts about what you have
determined from your analysis in completing the assignment. Nothing new
should be introduced in the conclusion that was not previously discussed
in the body paragraphs.
Include any tables of data or calculations, calculated values,
and/or graphs referenced in the paper. (Note: The minimum required
length excludes any tables or graphs.)
Document formatting, citations, and style should conform to the CSU Global Guide to Writing and APA Requirements (Links to an external site.). A short summary containing much that you need to know about paper formatting, citations, and references is contained in the Template Paper (Links to an external site.). In addition, information in the CSU Global Writing Center (Links to an external site.) has many helpful areas (Writing Tips, Template & Examples/Papers & Essays, Figures and Tables, and others).
NOTE: You MUST submit your Excel file with your

Problem 8 The mean starting salary for nurses is $67,694 nationally ("Staff nurse -," 2013).The standard deviation is approximately $10,333. Assume that the starting salaryis normally distributed. a.) State the random variable. b.) Find the probability that a starting nurse will make more than $80,000. c.) Find the probability that a starting nurse will make less than $60,000. d.) If a nurse made less than $50,000, would you think the nurse was under paid? Why or why not? Problem 9 The WHO MONICA Project collected blood pressure data for people in China (Kuulasmaa, Hense&Tolonen, 1998). Data based on information from the study is in table #6. Determine if the data is from a population that is normallydistributed. Table #6: Blood Pressure Values for People in China 114 141 154 137 131 132 133 156 119 138 86 122 112 114 177 128 137 140 171 129 127 104 97 135 107 136 118 92 182 150 142 97 140 106 76 115 119 125 162 80 138 124 132 143 119 Problem 10 The size of fish is very important to commercial fishing. A study conducted in2012 found the length of Atlantic cod caught in nets in Karlskrona to have a meanof 49.9 cm and a standard deviation of 3.74 cm (Ovegard, Berndt &Lunneryd, 2012). The length of fish is normally distributed. A sample of 15 fish is taken. a.) State the random variable. b.) Find the mean and standard deviation of the sample mean. c.) Find the probability that the sample mean length of the Atlantic cod is lessthan 52 cm. d.) Find the probability that the sample mean length of the Atlantic cod is morethan 74 cm. e.) If you found sample mean length for Atlantic cod to be more than 74 cm, whatcould you conclude?

Chamberlain College of Nursing Weights of 50 Babies at Birth Research Paper
Required ResourcesRead/review the following resources for this activity:Textbook: Chapter 8LessonScenario/SummaryYou will complete a Course Project in this course that will span two weeks. The final project is due the Sunday of Week 7. The project is broken into two parts. You will complete Part I in Week 6 and Part II in Week 7. In Week 6, Confidence Intervals will be explored and in Week 7 Hypothesis testing will be explored.A confidence interval is a defined range of values such that there is a specified probability that the value of a parameter lies within the interval.In Part I of this project, you will pick a topic, complete research and provide a write-up that includes calculations. Round all values to two decimal places when appropriate.DeliverablesChoose a Topic where you can gather at least 50 pieces of data.Examples of TopicsThe Golden Gate Warriors Points Per Game in 2016 (use the points scored in the first 50 games).High School Graduation Rates by State (use the graduation rates for all 50 states)Average Tuition Rates in the US (You have to find the tuition rates of 50 college/universities).The prices of a hotel room per night in a major city (You have to find the price of the same night of hotels in one city).Weights of 50 babies at birth.Write at least a 1-Page ReportOpen a Word DocumentIntroduction--Provide a description of your topic and cite where you found your data.Sample Data—Include a 5x10 table including your 50 values in your report. You must provide ALL of your sample data.Problem Computations—For the topic you chose, you must answer the following:Determine the mean and standard deviation of your sample.Find the 80%, 95%, and 99% confidence intervals.Make sure to list the margin of error for the 80%, 95%, and 99% confidence interval.Create your own confidence interval (you cannot use 80%, 95%, and 99%) and make sure to show your work. Make sure to list the margin of error.Problem Analysis—Write a half-page reflection.What trend do you see takes place to the confidence interval as the confidence level rises? Explain mathematically why that takes place.Provide a sentence for each confidence interval created in part c) which explains what the confidence interval means in context of topic of your project.Explain how Part I of the project has helped you understand confidence intervals better?How did this project help you understand statistics better?Required SoftwareMicrosoft Office: Word and ExcelUse a personal copy or access the software at https://application.chamberlain.edu (Links to an external site.).GradingThis activity will be graded based on the Course Project grading rubric.
