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.

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.

STA 3215CBE Rasmussen Independent and Dependent Samples Hypothesis Tests Worksheet
CompetencyFormulate and evaluate hypothesis tests for population parameters based on sample statistics using both Critical Regions and P-Values, and be able to state results in a non-technical way that can be understood by consumers of the data instead of statisticians.Student ProfileYou are a statistician working for a drug company. A few new scientists have been hired by your company. They are experts in pharmacology, but are not experts in doing statistical studies, so you will explain to them how statistical studies are done when testing two samples for the effectiveness of a new drug. The two samples can be dependent or independent, and you will explain the difference.Concept being StudiedYour focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters.What to SubmitYour research and analysis should be presented on the attached Word documentprovided. All calculations should be provided on a separate Excel workbook that that is attached and should be submitted to your boss as well.
