MATH 399N Week 8: Math in the Real World (2022/2023) We rely heavily on statistics and statistical research in the health and helping professions. The outcomes from this work help us identify the best methods for helping and caring for clients and patients. Discuss at least two concepts from the course that you can use in your future career. Be sure to state the concept, how you would use it, and why that approach would be the best approach for the situation.

MATH 399N Week 7 discussion: Rejection Region (latest 2022/2023) How is the rejection region defined, and how is that related to the p value? When do you reject or fail to reject the null hypothesis? Why do you think statisticians are asked to complete hypothesis testing? Can you think of examples in courts, in medicine, or in your area?

MATH 399N Week 2 discussion: Regression 2022/2023 Suppose you are given data from a survey showing the IQ of each person interviewed and the IQ of his or her mother. That is all the information that you have. Your boss has asked you to put together a report showing the relationship between these two variables. What could you present and why?

MATH 399N Week 1 Discussion: Descriptive Statistics 2022/2023 If you were given a large data set (i.e., sales over the last year of our top 100 customers), what might you be able to do with these data? What might be the benefits of describing the data?

Statistical Concepts: 2022/2023 Data Simulation Confidence Intervals Normal Probabilities Short Answer Writing Assignment All answers should be complete sentences. We need to find the confidence interval for the SLEEP variable. To do this, we need to find the mean and then find the maximum error. Then we can use a calculator to find the interval, (x – E, x E). First, find the mean. Under that column, in cell E37, type =AVERAGE(E2:E36). Under that in cel...

Statistical Concepts: 2022/2023 Probability Binomial Probability Distribution Calculating Binomial Probabilities Open a new Excel worksheet. Open spreadsheet In cell A1 type “success” as the label Under that in column A, type 0 through 10 (these will be in rows 2 through 12) In cell B1, type “one fourth” In cell B2, type “=BINOM.DIST(A2,10,0.25,FALSE)” [NOTE: if you have Excel 2007, then the formula is BINOMDIST without the period] Then copy and paste ...
