Question

Introduction: Assume that you have the following hypothetical data. Use the data to complete the following requirements. Dataset: Lab 4.sav Requirements: Question 1: Generate the descriptive statistics and perform an appropriate statistical analysis to determine whether state median household income is related with fatality rate across states. a. Report and interpret your statistical results, as well as create tables/figures in accordance with the APA guideline for the professional audience. b. Also, briefly address the results and their impacts written for a lay audience. Question 2: Investigate whether state median household income predicts fatality rate across states. a. Report and interpret your statistical results, as well as create tables/figures in accordance with the APA guideline for the professional audience. b. Also, briefly address the results and their impacts written for a lay audience

Answer 1

Kindly provide some relevant data in this regard, so that we can show you the analysis...

As no data is given in the question, so I shall explain you a process that you can follow in order to perform the analysis...

Descriptive Analysis:

I have considered a sample data set in this case to show the results...

A scatter plot is shown below...

The scatter graph shows a negative correlation in the data which means as one variable increases, the other decreases...

1) Descriptive Analysis:

All the Parameters shown above are self explanatory...

2) Regression Analysis:

A regression analysis can be done in order to check whether state median household income predicts fatality rate across states.

The output is shown below:

Here the regression equation is:

Fatality = 816.15 - 0.174H

Where,

H = Household Income

If you have the data for the Household Income, you can directly predict the Fatality from this equation...

In this experiment, the value of R² is 0.9088 (refer the above output). as this value is closer to 1, the model is a good fit. This means that 90.88% of the variations in the dependent variable is explained by the independent variable which is good...

Moreover, the R value is 0.95 which is also good. this means that there is a strong relationship between the two variables...

Thus regression can be used to predict whether state median household income has any impact on fatality...

This solution is just given for the sample data set mentioned above. kind provide your responses so that we can give you a proper analysis...
