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.
Initial Post Instructions
Find an example of a confidence interval in the news, scholarly source or medical journal. Summarize the article/study. Does the article/study include the sample size and the level of confidence used to create the confidence interval? Explain what the confidence interval means in context of the news article or scholarly source.
Follow-Up Post Instructions
Respond to at least two peers or one peer and the instructor. Further the dialogue by providing more information and clarification.
Here are some suggested responses
How do you think the confidence interval that was presented in the study was calculated?
Explain the mathematical concepts could you extract from this article/study.
Minimum of 2 posts (1 initial & 1 follow-up)

This is a very easy assignment and a quick one because all the information you need is in the instructions which is basically the assignment, I just dont quite get it, please help me get it done quickly.
1. Identify which of the following values are valid and not valid numbers for a probability:
b. – 0.6
i. – 1/6
2. what is the probability of randomly selecting a diamond from a standard 52-card deck?
3. If the order of objects is of importance, how many ways can I select nine objects two at a time?
4. If the order of objects is not of importance, how many ways can I select nine objects two at a time?
Deadline is Oct. 5.
The last file is an example of how it should look like. For this assignment, you will be using Excel to conduct both univariate and bivariate data analyses.
Questions 1, 2 and 3 must be done in MS Excel software. the rest u can solve itmanualy. Please make sure you are following thr format
ALL WORK MUST BE SHOWN. You will submit a single Excel file to the Assignment Drop Box by the due date and time (see Schedule below). You must ensure that all work is shown and that all questions for the problem are answered. Before midnight on the due date, you must complete the assessment related to the assignment.

Please find problems in attachment
please add formula calculation and explanation on how you came to conclusion
STATA needed. please answer every question in the document I uploaded. You must submit both the hand- or type-written solutions and the Stata Do-file.
Now that you’ve gotten a foundation in research, data, and analysis you’ll be better prepared to review criminal justice studies and use relevant data to help you solve problems and make decisions. In this assignment, you’ll demonstrate your knowledge of how research and inferential statistics might be used in criminal justice operations, such as police, courts, and corrections.
Write an 875- to 1,050-word paper in which you do the following:
Describe your ideal job in criminal justice.
Explain how you might use published research statistics to help you solve problems and make decisions in your ideal job. Provide 2 examples of how you could use published criminal justice research in your ideal job.
Differentiate between correlation and causation in a way that connects to your ideal job.
Identify potential applications of correlation and regression within management or research for your chosen criminal justice field.
Describe how techniques involving association, correlation, and prediction (as in regression) help form policy and operational decisions for more effective criminal justice practices.
Cite a minimum of 2 peer-reviewed sources.
Format your paper according to APA guidelines.
Please solve the problems and show work. The bolded text is the answer please use this to check work! Please solve the onesthat have work done on them anyway!
