Make a conjecture through curiosity or observation and use it to make a claim that is testable through hypothesis testing.  Write a short paragraph explaining what lead you to this claim. This may be a claim similar to anything in chapter 10 or 11. Gather data to test your claim. Justify your choice in sampling. Include your raw data as an appendix. Perform the test on the data. Explain what compromises and assumptions you had to make. Explain and interpret…

Due Thursday  When our data aligns to the characteristics of normal distribution

Due Thursday  When our data aligns to the characteristics of normal distribution, it maintains specific properties that help us interpret results and make decisions.  Respond to the following in a minimum of 175 words: Discuss a situation where you can collect data, and the data the Empirical Rule applies, meaning that the data representing this situation follows a normal distribution. You are encouraged to conduct research using the internet to discover a situation that fits this criteria.  Citing your source,…

All of us are used to multiple choice tests. If all the exam questions have a choice of 4 different responses (a,b,c,d) what is the probability of randomly guessing the right answer? See! You are all naturally mathematicians! How does this relate to the formulas regarding probability? For example, if the probability of a correct answer was .25, what would the mean (aka expected value) of the distribution be if the sample size was 100? Hint: mean=np

Determining what variables to include in a multiple regression model can be very

Determining what variables to include in a multiple regression model can be very challenging. Consider a model with two nonsignificant variables and several significant variables. Removing either of the nonsignificant variables and rerunning the model causes the other nonsignificant variable to become significant. Why might this be happening? What factors would you consider when choosing what variable(s) to include in the final model? Embed course material concepts, principles, and theories (require supporting citations) along with at least one scholarly, peer-reviewed…

Suppose you are interested in the behaviors of physicians that have high ratings

Suppose you are interested in the behaviors of physicians that have high ratings of patient satisfaction. The research goal is to identify the behaviors in the natural clinical settings of these successful physicians so that these behaviors can be built into the curricula of medical preparation programs. The main data were collected by the video recording of five randomly selected physician-patient encounters from 10 physicians who have been rated highly by patients in a reliable satisfaction survey. Assume that you…

1 page discussion This week you will look at misleading information that you are  exposed to every day.  Find an example of a survey or poll or even a  tweet that you think might be misleading. How would you support your conclusions? You want to use statistical reasoning here not personal opinion. Places to look might be online polls where anyone can answer.  If the title of a survey is misleading, how would you correct it?  Was the sample representative?  Be…
