Moore College of Art and Design Ages of The Oscar Best Actor Winners Histogram
CONTEXTWe will use the Best Actor Oscar winners (1970–2001) data file to learn how to create a histogram using StatCrunch, and to practice what we've learned about describing a histogram. We are interested in describing the distribution of actors' ages when they won the Best Actor Oscar.PROMPTIn your initial post, respond to the following discussion prompt. Describe the distribution of ages of the Best Actor Oscar winners. Your description should include: shape, center (a typical representative age), a typical interval of representative ages, spread (overall range of ages), and any outliers (unusual ages). Be sure to embed your histogram in your initial post Please do not submit your histogram as an attachment.Create a second histogram for the distribution of ages, and adjust the bin width . Try both smaller and larger bin widths. Choose a bin width so that your second histogram does not look like the first. Upload your second histogram to your Stats-Class folder. Also embed your second histogram with your initial post. Indicate which histogram is better for analyzing the data (your first embedded histogram or your second). Explain why.

Week 6 Discussion: Confidence Intervals
Confidence Intervals
In everyday terms, a confidence interval is the range of values around a sample statistic (such as mean or proportion) within which clinicians can expect to get the same results if they repeat the study protocol or intervention, including measuring the same outcomes the same ways. As you ask yourself, "Will I get the same results if I use this research?", you must address the precision of study findings, which is determined by the Confidence Interval. If the CI around the sample statistic is narrow, you can be confident you will get close to the same results if you implement the same research in your practice.
Consider the following example. Suppose that you did a systematic review of studies on the effect of tai chi exercise on sleep quality, and you found that tai chi affected sleep quality in older people. If, according to your study, you found the lower boundary of the CI to be .49, the study statistic to be 0.87, and the upper boundary to be 1.25, this would mean that each end limit is 0.38 from the sample statistic, which is a relatively narrow CI.
(UB + LB)/2 = Statistic [(1.25 + .49)/2 = .87]
Keep in mind that a mean difference of 0 indicates there is no difference; this CI does not contain 0. Therefore, the sample statistic is statistically significant and unlikely to occur by chance.
Because this was a systematic review, and tai chi exercise has been established from the studies you assessed as helping people sleep, based on the sample statistics and the CI, clinicians could now use your study and confidently include tai chi exercises among possible recommendations for patients who have difficulty sleeping.
Now you can apply your knowledge of CIs to create your own studies and make wise decisions about whether to base your patient care on a particular research finding.

Statistical Analysis Report Worksheet
InstructionsYou are currently working at NCLEX Memorial Hospital in the Infectious Diseases Unit. Over the past few days, you have noticed an increase in patients admitted with a particular infectious disease. You believe that the ages of these patients play a critical role in the method used to treat the patients. You decide to speak to your manager, and together you work to use statistical analysis to look more closely at the ages of these patients.You do some research and put together a spreadsheet (attached) of the data that contains the following information:Client numberInfection disease statusAge of the patientYou are to put together a PowerPoint presentation that explains the analysis of your findings which you will submit to your manager. The presentation should contain all components of your findings. For review, the components of the report should include:Brief overview of the scenario and variables in the data setDiscussion, calculation, and interpretation of the mean, median, mode, range, standard deviation, and varianceDiscussion, construction, and interpretation of the 95% confidence intervalExplanation of the full hypothesis testConclusionThe calculations should be performed in your spreadsheet that you will also submit to your manager. You can find additional information on what to add to your PowerPoint presentation in this Word document (attached). Use the questions in the worksheet as your guide for the contents of your presentation.For your final deliverable, submit your PowerPoint presentation and the Excel workbook showing your work. MUST MEET THE FOLLOWING REQUIREMENTS! All problems are solved correctly. Complete and detailed steps are provided to explain how to solve the problem. Explanations demonstrate a mastery of understanding of the statistical concepts and terminology. All variables, equations, and expressions are properly formatted.
