- Probabilistic Inference and Statistical Methods in Network Analysis examines various aspects of network analysis and analysis several dimensions of probabilistic inferences.It includes an in-depth social network analysis over clinical education of diabetic footand also on online social network software. The book provides the reader with the insightsinto the development of network analysis by using various statistical methodologies,so as to understand the dynamics of networking. Using words to describe what the article is about and how it uses statistics. What is the material and methods?In hypothesis testing, if you find significance, does that mean that your study has meaning? Explain. _______________________________________________Question( A scientific group claims that the true population mean μ is more than 7 meters.

- The power of a test is measured by its capability of _______________ a. not rejecting a null hypothesis that is false. b. rejecting a null hypothesis that is false. c. not rejecting a null hypothesis that is true. d.rejecting a null hypothesis that is true.Obtaining the P-value. Let x denote the test statistic for a hypothesis test and x0 its observed value. Then the P-value of the hypothesis test equals a. P(x ≥ x0) for a right-tailed test,b. P(x ≤ x0) for a left-tailed test,c. 2 min{P(x ≤ x0), P(x ≥ x0)} for a two-tailed test, where the probabilities are computed under the assumption that the null hypothesis is true. Suppose that you are considering a one-mean z-test. Verify that the probability expressions in parts (a)–(c) are equivalent to those obtained in Exercise. Consider a one-mean z-test. Denote z0 as the observed value of the test statistic z. If the test is right tailed, then the P value can be expressed as P(z ≥ z0). Determine the corresponding expression for the P-value if the test is a. left tailed. b. two tailed.18-34 35-49 50-64 65+ Burger King 127 119 63 163 McDonald's 75 142 82 129 Wendy's 124 156 75 132
