Pick any two variables that you feel may be related and estimate what you think the strength of the correlation coefficient would be for those two variables.In your response, estimate the value of r.  For example, specify a strong (.7 to .9), medium (.4 to .6), or low (0 to .3) value for r.  The value of the coefficient can be positive or negative.  For example, consider an increase in police patrols in a neighborhood and the number of burglaries that occur in that neighborhood.  I would say that would be a strong inverse relationship with an r-value of -0.8; as one (patrols) increases, the other (burglary rate) goes down.  Describe the factors that you think would contribute to why the variables would have the relationship that you estimate it to be.

Select a discrete probability distribution and present a real-life application of that distribution. Interpret the expected value and the standard deviation of your selected distribution within the context of the real-life example that you have selected, and describe how these values can be used by enterprise decision-makers. Select a continuous probability distribution and present a real-life application of that distribution. Interpret the expected value and the standard deviation of your selected distribution within the context of the real-life example that you have selected, and describe how these values can be used by enterprise decision-makers.

Understanding descriptive statistics, their measures of center and their variability helps form the foundation of statistical analysis. Descriptive statistics tell us how frequently an observation occurs, what is considered average, and how far data in our sample deviate from being average. With these statistics, we are able to provide a summary of characteristics from both large and small datasets. Measures of central tendency and variability provide valuable information on their own and form the cornerstone of the quantitative structures that we build in our research studies. Required Resources Read/review the following resources for this activity: OpenStax Textbook: Chapter 2 Lesson Minimum of 1 scholarly source In your reference for this assignment, be sure to include both your text/class materials AND your outside reading(s). Initial Post Instructions For this Discussion, you will examine the central tendency and variability in terms of pulse rate. Find and record the pulse rate of 10 different people where you work. Tell us a little about the population from which you drew your data. Describe your findings in terms of central tendency and variability. Consider using some of the following to help you form your initial discussion post: What are your measures of central tendency (i.e., mean, median, and mode)? Which might be the better measure for central tendency and why? What is the standard deviation of your data? How variable are the data (range)? Are there any outliers? Investigate possible reasons for these outliers, and things that might limit them if the further study were to be carried out. What are some variables that should be considered in discussing your measures of central tendency and variation? Is there any skewness in your measured data? How would you describe this data (i.e. what insights did you gain from this data)?

You are working with a middle school class that loses focus easily and over half of the students struggle with fraction concepts. Design a bridging activity linking addition and subtraction of fractions to an abstract, pencil and paper assignment. Be sure to explain the teaching sequence carefully as if leaving exact notes for a substitute teacher who has never seen or used the activities before. Include some scripting as well. I will attach the chapter notes i have taken, please review them carefully and use appropriate terminology and procedures outlined in the notes.

Determine the solutions in the interval [?2?, 2?] to the following trigonometric equation. You may leave one of your solutions in the exact form x = arccos y. You must show all of your steps. Mysterious or unsupported work will not be counted. 1 + cos2 x = 2 sin x 2.

For this assignment, please watch the following video (copy and paste if the link doesn’t work): https://nutritionfacts.org/how-not-to-diet/ (Links to an external site.) Evidence-based is key, not hearsay nor anecdotal evidence does it but statistics! 🙂 This is evidence-based methods for losing weight, losing fat. This will always be good to know for everyone. So you are welcome. Watch the video as much as you like but see at least two hypothesis tests with p-values, (like p < .001) and at least two confidence intervals and at least two graphs. You will probably want to watch the whole thing. Watch at least the first 20 minutes of it. Then please comment on impressed you and what you would want to tell others. State a hypothesis test with a p-value and a confidence interval and state what they both meant and what they show. This will also show that you actually watched it which is necessary to show for this assignment. It will be graded on 4 points for a confidence interval and what it meant, 4 points on stating a hypotheses test with a p-value and what it means, and 1 point each for responding to others. Minus one point as always if it's done lately.
