- This is a problem using the empirical ruleCan you please explain how to solve part i, using both the empirical rule and using a Z table?Our goal is to see whether the global temperatures has been getting higher. For the phrase above, assume the data has already been presented and state a hypothesis. Describe the process one should take to test the hypothesis in detail. How should someone plan to test a hypothesis? Under what circumstances can somebody conclude that the global temperatures has been getting higher?
- I am having difficulty with The Analysis of Biological Data chapter 10 question 15AP, I need to check my solutions but there are none posted for me to review. If I could compare answers that would be great.A question about the empirical rule that I don't quite understandwhich of the following best describes where a results section is placed in a quantitative research paper? 1. No page break, immediately after the methods section 2. New page, immediately after the method section 3. No page break, immediately after the discussion 4. New page, immediately after the discussion
- Hi, Based on the attachment: Note that the coefficient on Children i is not statistically different from zero. In light of that fact, would you recommend dropping this variable from the model? Why or why not?Which model—the one for parliaments or the one for ministries (or cabinets)—presented in the article has the greater explanatory power? How can you tell?A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One position supported running on soft surfaces to relieve joints that were in recovery from injury. The second position supported running on hard surfaces since soft surfaces can be uneven, which may make worse those injuries a soft surface was intended to help. Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to support either position, which of the following hypotheses would be appropriate? 1. The second position makes the more sense, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the first position. 2. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test. 3. Because there is uncertainty, we should postpone…
- Compare the two separate scatterplots. In particular, how do the associtation compare between women with pets vs. women without pets? Does one group have more variation in systolic blood pressure than the other? If so, for which group? Does systolic blood pressure seem higher for common ages between the two groups? If so, for which group?Use the empirical rule to answer the following questions
