ALU Correlation Between Resting and After Exercise Heartbeat Rates Questions
In this lesson, you will run a correlation between the resting and after exercising heart rates to determine if a linear relationship exists between the two variables and how strong the relationship is. Steps Open the Heart Rate Dataset in Excel and identify the X-variable (resting heart rates for all 200 participants) and the Y-variable (after exercise heart rates for all 200 participants). Use the Scatter Plot function in the Insert Charts section of Excel to create a scatter plot of the X and Y variables Add a trendline to the scatter plot Use the Data Analysis tools in Excel to find the regression equation. In a Word document, describe the relationship between the X-variable (resting heart rate)and the Y-variable (after exercise heart rate). Graph the scatter plot with a trend line. Does it appear there is a linear relationship? What does this mean? Calculate the correlation coefficient r using excel. Is this r (value) high compared to +1? Based on the correlation coefficient is the relationship strong? Use excel to find the regression equation. Identify the slope. What does it tell us in terms of our heart rate data?

Grand Canyon University Gestational Diabetes Case Study
please use the number 6 for this question please: A patient is classified as having gestational diabetes if their average glucose level is above 140 milligrams per deciliter (mg/dl) one hour after a sugary drink is ingested. Rebecca's doctor is concerned that she may suffer from gestational diabetes. There is variation both in the actual glucose level and in the blood test that measures the level. Rebecca's measured glucose level one hour after ingesting the sugary drink varies according to the Normal distribution with μ= 140+# mg/dl and σ = #+1 mg/dl, where # is the last digit of your GCU student ID number. Using the Central Limit Theorem, determine the probability of Rebecca being diagnosed with gestational diabetes if her glucose level is measured:Once?#+2 times, where # is the last digit of your student ID?#+4 times, where # is the last digit of your student ID?Comment on the relationship between the probabilities observed in (a), (b), and (c). Explain, using concepts from lecture why this occurs and what it means in context. 2. Suppose next that we have even less knowledge of our patient, and we are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 9# percent reliable, this means that the test will yield an accurate positive result in 9#% of the cases where the disease is actually present. Gestational diabetes affects #+1 percent of the population in our patient’s age group, and that our test has a false positive rate of #+4 percent. Use your knowledge of Bayes’ Theorem and Conditional Probabilities to compute the following quantities based on the information given only in part 2:If 100,000 people take the blood test, how many people would you expect to test positive and actually have gestational diabetes?What is the probability of having the disease given that you test positive?If 100,000 people take the blood test, how many people would you expect to test negative despite actually having gestational diabetes?What is the probability of having the disease given that you tested negative?Comment on what you observe in the above computations. How does the prevalence of the disease affect whether the test can be trusted?3. As we have seen in class, hypothesis testing and confidence intervals are the most common inferential tools used in statistics. Imagine that you have been tasked with designing an experiment to determine reliably if a patient should be diagnosed with diabetes based on their blood test results. Create a short outline of your experiment, including all of the following:A detailed discussion of your experimental design.How is randomization used in your sampling or assignment strategy?The type of inferential test utilized in your experiment.A formal statement of the null and alternative hypothesis for your test.A confidence interval for estimating the parameter in your test.An interpretation of your p-value and confidence interval, including what they mean in context of your experimental design

Inferential Statistics Article Critique
[WLOs: 3, 4, 5, 6] [CLOs: 1, 2, 3, 4]
Prior to beginning work on this assignment, review the assigned readings and the instructor guidance for the week, complete the learning activity, read the Ashford Writing Center resource Writing an Article Critique (Links to an external site.), view the Ashford University Library tutorial How to Read a Scholarly Article (Links to an external site.), and review the required video Test statistics: Crash Course statistics #26 (Links to an external site.). Your instructor will post an announcement with the reference for the article to be critiqued in this assignment. Read the article assigned by your instructor and identify the research questions and/or hypotheses as they are stated. Consider the following questions: What are the variables (sample sizes, population, treatments, etc.)? What are the inferential statistics used in this article? Were the proper steps of hypothesis testing followed?
Your article critique paper must
Determine what question(s) the authors are trying to answer by doing this research, the hypothesis being tested, and the concepts that were applied in this process.
Evaluate the article and critique the statistical analysis employed in the study.
Identify the specific statistical tests used. Were the tests appropriate for the situation and type of data?
Would you have included more and/or different variables? Explain your answer.
Examine the results, assumptions, interpretations, and limitations of the statistical study.
Interpret the findings of the author(s) using statistical concepts.
What would you have done differently? Why?
Discuss how either the statistical test(s) used in this study or the findings of this research might be useful in your future career.
The Inferential Statistics Article Critique assignment
Must be three to four double-spaced pages in length (not including title and references pages) and formatted according to APA Style as outlined in the Ashford Writing Center’s APA Style (Links to an external site.)
