Hypothesis Testing and Confidence Intervals
Complete the following four hypotheses, using α = 0.05 for each.Mean sales per week exceeds 41.5 per salespersonProportion receiving online training is less than 55%Mean calls made among those with no training is less than 145Mean time per call is greater than 15 minutesUsing the same data set from part A, perform the hypothesis test for each speculation in order to see if there is evidence to support the manager's belief. Use the Seven Elements of a Test of Hypothesis from Section 7.1 of your text book, as well as the p-value calculation from Section 7.3, and explain your conclusion in simple terms.Compute 99% confidence intervals for each of the variables described in a.-d., and interpret these intervals.Write a report about the results, distilling down the results in a way that would be understandable to someone who does not know statistics. Clear explanations and interpretations are critical.All DeVry University policies are in effect, including the plagiarism policy.Project Part B report is due by the end of Week 6.Project Part B is worth 100 total points. See grading rubric below.

Grantham University W7 Coefficient of Determination Worksheet
Week 7 AssignmentQuestion 1Assume you have noted the following prices for paperback books and the number of pages that each book contains.Develop a least-squares estimated regression line.Compute the coefficient of determination and explain its meaning.Compute the correlation coefficient between the price and the number of pages. Test to see if x and y are related. Use α = 0.10.Question 2The following data represent a company's yearly sales volume and its advertising expenditure over a period of 8 years.Develop a scatter diagram of sales versus advertising and explain what it shows regarding the relationship between sales and advertising.Use the method of least squares to compute an estimated regression line between sales and advertising.If the company's advertising expenditure is $400,000, what are the predicted sales? Give the answer in dollars.What does the slope of the estimated regression line indicate?

Statistical Significance
To prepare for this Discussion:Review the Learning Resources related to hypothesis testing, meaningfulness, and statistical significance.Review Magnusson’s web blog found in the Learning Resources to further your visualization and understanding of statistical power and significance testing.Review the American Statistical Association’s press release and consider the misconceptions and misuse of p-values.Consider the scenario:A research paper claims a meaningful contribution to the literature based on finding statistically significant relationships between predictor and response variables. In the footnotes, you see the following statement, “given this research was exploratory in nature, traditional levels of significance to reject the null hypotheses were relaxed to the .10 level.”By Day 3Post your response to the scenario in which you critically evaluate this footnote. As a reader/reviewer, what response would you provide to the authors about this footnote?Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

STAT 200 UM Effective Campaign Against Drug and Substance Abuse Discussion
Probability in Everyday LifeProbability tells us the chance or likelihood that a particular event will occur. Whether or not we realize it, every day we use probability to make decisions. For instance, when deciding whether to take an umbrella, we check the weather forecast to see the probability that it will rain. In this instance, probability tells us the likelihood that it will rain; however, the decision about taking an umbrella is based on an individual’s willingness to risk getting rained on. Some people will take an umbrella, when the probability of rain is at least 40%, while others will wait until the probability is at least 60%.What is an example from your own life or in your workplace, where you have used probability to make a decision?
