Data Analysis in R

1)     Read the income dataset, “zipIncomeAssignment.csv”, into R. (You can find the csv file in iLearn under the Content -> Week 2 folder.)

2)     Change the column names of your data frame so that zcta becomes zipCode and meanhouseholdincome becomes income.

3)     Analyze the summary of your data. What are the mean and median average incomes?

4)     Plot a scatter plot of the data. Although this graph is not too informative, do you see any outlier values? If so, what are they?

5)     In order to omit outliers, need to subset of the data so that:

xxσ26s2116.2

(a) What is the level of significance? 

State the null and alternate hypotheses.

Ho: σ2 < 136.2; H1: σ2 = 136.2

Ho: σ2 = 136.2; H1: σ2 ≠ 136.2    

Ho: σ2 = 136.2; H1: σ2 < 136.2

Ho: σ2 = 136.2; H1: σ2 > 136.2

(b) Find the value of the chi-square statistic for the sample. (Round your answer to two decimal places.) 

What are the degrees of freedom? 

What assumptions are you making about the original distribution?

We assume a normal population distribution.

We assume a exponential population distribution.    

We assume a binomial population distribution.

We assume a uniform population distribution.

(c) Find or estimate the P-value of the sample test statistic. 

P-value > 0.100

0.050 < P-value < 0.100    

0.025 < P-value < 0.050

0.010 < P-value < 0.025

0.005 < P-value < 0.010

P-value < 0.005

(d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis?

Since the P-value > α, we fail to reject the null hypothesis.

Since the P-value > α, we reject the null hypothesis.    

Since the P-value ≤ α, we reject the null hypothesis.

Since the P-value ≤ α, we fail to reject the null hypothesis.

(e) Interpret your conclusion in the context of the application.

At the 1% level of significance, there is insufficient evidence to conclude that the variance for number of mountain climber deaths is less than 136.2

At the 1% level of significance, there is sufficient evidence to conclude that the variance for number of mountain climber deaths is less than 136.2    

(f) Find the requested confidence interval for the population variance. (Round your answers to two decimal places.)lower limit 

upper limit     

Interpret the results in the context of the application.

We are 90% confident that σ2 lies outside this interval.

We are 90% confident that σ2 lies below this interval.    

We are 90% confident that σ2 lies above this interval.

We are 90% confident that σ2 lies within this interval.

America has been a country of choice for most would-be immigrants because of many advantages and benefits it offers such as political freedom, a good educational system, and a good economy that gives hardworking people a real chance of realizing their goals in life such as the attainment of the “American Dream” of a well-paying, stable job and a comfortable urban lifestyle. These and many more make America a perpetual magnet for immigrants. In its early years, America welcomed immigrants with open arms with Thomas Jefferson complaining that the English King George III had deliberately prevented emigrants from coming over to America as revenge for its former prized and largest colony fighting to gain its own independence.

The young nation back then was largely an open and empty space and it needed new immigrants to make the country progress and attain its promise and potential as a global power in economic, political, and military terms. America did attain its stated aims in a matter of just a few centuries since birth and is today considered the sole superpower largely due to the contributions of its immigrants in the fields of science, economics, engineering, and other areas.

The great nation of America was founded on the back-then experimental idea of having less government and more personal civil liberties and political freedoms for its varied citizens. In many ways, this basic democratic principle had worked perfectly well as people went about their own business with minimal interference from the federal and state governments. The very first Congress after independence established uniform rules for naturalization of new immigrants to help assimilate them into mainstream society. All immigrants were made eligible, subject to certain minimum qualifications, for all the elective federal offices except for the positions of president and vice president as a
