Data was collected by the American Consumer Survey as a part of the Census in the year 2013. The data was discussed in this project is the income of White Women, Black Women and All Males…. (continue with your introduction of the topic- DO NOT COPY MINE). The first(later you will use next) part of this study will look at (Fill in with the test you will be doing). The results of that test can be seen here.

Input the image of the results. Please adjust it to be of appropriate size to be seen and for one graph to not take up an entire page. You can make the images smaller to fit nicely in the paper. *If you have multiple images, shrink them to all fit in a single row.

Discuss your findings: We can see from the graph/table etc… Whatever you have to discuss here from the first test you should. The more specific with the values and data the better.

The next part of this study will look at the (fill in the test). You can then explain why you may run this test, or what kind of things it will show…. The results of that test can be seen here:

Statcrunch Chapter 11

This project requires you to look at income data from 51 different areas (50 states and D.C.). This data has a column for each of the following: White Women, Black Women, All Men. This is actual data comprised from the Census 2013 American Consumer Surveys. The goal is to work with real data, run statistics and draw conclusion on the difference or similarities in income based on race. There are 5 parts to this project that you will work on during 5 different weeks of the course. You will be writing conclusions, differences and similarities between the data sets after each part so in the end you have a complete report that will be submitted. In the end your findings should discuss the discrepancies in income based on race. Each week I will grade your submission and provide feedback on parts you should redo before completing the final project at the end of the semester.

Part 5

Task 1: Open the Income data set in Statcrunch.

Task 2: Construct a 95% confidence interval for the average difference in the means between White Women and Black Women’s income.

Task 3: Construct a 95% confidence interval for the average difference in the means between White Woman’s income and the Male income.

Task 4: Write your conclusion from the hypothesis test, being sure to include the hypotheses, P-value, and if we reject or do not reject the null. List the confidence interval and be sure to write an interpretation sentence.

***Step by Step directions for Statrcrunch are on the following Pages

***Please follow formatting guidance provided in the case study template

Performing a paired t test:

Make sure you have opened the Income data set. Click Stats T-Stats Paired. For sample 1 select White Women. Sample 2 will be Black Women. The hypothesis test we wish to perform will be a greater than test. Click Compute.

Graphical user interface, application  Description automatically generated

Make sure you highlight, copy and paste this data into your write up.

Constructing a Paired Mean Confidence Interval:

Click Stats T-Stats Paired. For sample 1 select White. Sample 2 will be Male. This time select confidence interval. There is no need to change the confidence level as we want a 95% confidence level. Click Compute. Make sure you highlight, copy and paste this data into your write up.

Now type your findings for the week. Write your conclusion from the hypothesis test, being sure to include the hypotheses, P-value, and if we reject or do not reject the null. Did it make a difference if you use alpha of .01 versus alpha of .10? List the confidence interval and be sure to write an interpretation sentence. Please review how we write out conclusions. There is/is not sufficient evidence… We are ___% confident the mean difference … Why are the values in this confidence interval negative?

Please refer to the formatting guidelines on the case study template

The provided data presents summary statistics for three groups: White, black, and the overall.

Based on the mean values, White people have an average income of $64,430.885, which is the highest, then the overall mean of $59,842.692, and the Black group has the lowest income at $40,358.596. The same trend is observed in the median income, where White individuals have the highest median at $60,959.5, followed by the overall median of $58,848, and Black individuals with a median of $38,572.5.

The spread of data, as indicated by the range, is widest for White individuals (range: The highest range was women ($21,138-$132,040), followed by the overall range ($20,166-$82,604), and then Black individuals (range: $ 19,496-$70,100). This implies greater income inequality amongst Whites.

Looking at boxplots would probably give a better idea of the income distribution within each group. Both minimum and maximum values and the interquartile range (Q3-Q1) provide information about spread and central tendency. Outliers can also be detected.

Overall, the data points to large income conferences between Whites and Blacks. White individuals usually have higher mean and median incomes and a more comprehensive income range. Analyzing boxplots would allow a visual representation of these differences, giving a more intricate perception of the income distribution within each group.

White is the race that has a higher income (M=64430.89, SD=15127.56)

than the Black/African American. Black/African has ana average income of

40358.596 with a standard deviation of 9276.80. The overall average income

of the two races is 59842.69 with a standard deviation of 11637.34. The

histogram shows that the income of the black/African American is skewed to

the right.

Interpretation Sentences:

1. We are 90% confident that the average income for overall individuals is

between $57,139.104 and $62,546.281.

2. We are 90% confident that the average income for Black/African American

individuals is between $60,916.447 and $67,945.322.

3. We are 90% confident that the average income for white individuals is

between $38,203.408 and $42,513.784.

4. We are 98% confident that the average income for overall individuals is

between $55,966.781 and $63,718.604.

5. We are 98% confident that the average income for Black/African American

individuals lies between $37,268.881 and $43,448.311.

6. We are 98% confident that the average income for White individuals lies

between $59,392.526 and $69,469.243.

Discussion on Confidence Levels:

As the confidence level increases, strides from 90% to 98%, variability of confidence

intervals also grows. Such an increase in the CI length demonstrates that the collected data

provide a higher level of accuracy in estimating the population parameter. This indicates

that, as such confidence levels increase, the flux of possible population means gets larger

and the area of the range exceeds other values.
