stats, rad and post answers only
show work in Microsoft word and uploadFor the following data:(a) Use Excel or another software to draw the scatter plot for the variables. You can either upload the file or copy the scatterplot into the text box for your answer.(b) Visually, determine whether there is a linear correlation between the two variables and, if so, determine whether it is positive or negative.(c) Using statistical methods, test the significance of the correlation coefficient at an alpha value of 0.05. Compare these results with your results from (b).The director of an alumni association for a small college wants to determine whether there is any type of relationship between the amount of an alumnus's contribution (in dollars) and the years the alumnus has been out of school. The data follow. Years x 1 5 3 10 7 6Contribution y 500 100 300 50 75 802. For the following data: (a) Use Excel or another software to draw the scatter plot for the variables. You can either upload the file or copy the scatterplot into the text box for your answer.(b) Visually, determine whether there is a linear correlation between the two variables and, if so, determine whether it is positive or negative.(c) Using statistical methods, test the significance of the correlation coefficient at an alpha value of 0.05. Compare these results with your results from (b). The average normal daily temperature (in degrees Fahrenheit) and the corresponding average monthly precipitation (in inches) for the month of June are shown here for seven randomly selected cities in the United States.

Compare these results with your results from (b).An environmentalist wants to determine the relationships between the numbers (in thousands) of forest fires over the year and the number (in hundred thousands) of acres burned. The data for 8 recent years are shown.Number of fires x 72 69 58 47 84 62 57 45Number of acres burned y 62 42 19 26 51 15 30 154. Which of the following statements is true about the following conclusion drawn after finding that there is a significant correlation between annual personal income and years of education.Conclusion: More education causes a person's income to rise.A. The conclusion cannot be drawn because correlation does not necessary implies causality.B.The conclusion is correct since the correlation is significant.C. The conclusion is incorrect; Instead we should conclude that annual personal income increases more years of education.D. No answer text provided.

Week 4 Discussion Questions
1. Many times, linear optimization is used to maximize an objective function because profit, productivity, or efficiency is the outcome of interest. Provide two examples where the goal is to optimize a process by minimizing an objective function. In your examples, identify the outcome and any constraints that would need to be met.2. When many constraints are present in a linear optimization problem, there is a greater chance that a redundant constraint exists. Assume you are trying to maximize an objective function and you have two decision variables, X1 and X2. If a redundant constraint exists, does the constraint become necessary if you try to minimize (instead of maximize) the same objective function? Why? Do you need an objective function to determine if a constraint is redundant? Explain.

MAT 205 UA Knowledge of The Math Applications Journal
Mathematics in the Real-World
Here is a list of many such application concepts that were discussed throughout the book:
Global melting (page 70)
Save money and save the earth (page 99)
Federal budget (page 173)
How numbers can deceive polygraph, mammogram, and more (page 178)
Measuring your money by understanding tax, interests, investments, loans, budget, etc. (Chapter 4)
Should you believe a statistical study (Chapter 5B)
Graphics in the media (Chapter 5D)
Correlation and causality (Chapter 5E)
Is polling reliable (page 414)
Exponential and logarithmic scales and their use in understanding acidification of lakes and oceans and effect of exponential population rise (Chapter 8)
Ocean acidification (page 526)
Climate modeling (page 534)
Mathematics of politics (Chapter 12)
For this journal entry, choose any two application problems from the above list and answer the following questions.
What are the two topics that you have chosen?
Why did you choose the topics?
How will you use the applications in your own life? Be very specific.
How can you use the applications in your own community? For example, if you believe in climate change and you find that your senator, congressperson, or members of your town council do not believe in climate change, how can you use your knowledge to change their beliefs? This is just an example. You can use this or your own examples and ideas to discuss how you can use your applications for the betterment of the society and the country.
Did you know about all these math applications before you took the class? How has your perspective about math changed after taking this class?
Were you afraid of math before taking this class? Are you still afraid? Why or why not?
Reflect on your journey through the 5 weeks of this class.
