In the paper “Reassessment of TL Age Estimates of Burnt Flint from the Paleolithic Site of Tabun Cave, Israel” (Journal of Human Evolution, Vol. 45, Issue 5, pp. 401–409), N. Mercier and H. Valladas discussed the re-dating of artifacts and human remains found at Tabun Cave by using new methodological improvements. A random sample of 18 excavated pieces yielded the following new thermo luminescence (TL) ages.
Decide whether applying the t-test to perform a hypothesis test for the population mean in question appears reasonable. Explain your answers.
Answer to relevant QuestionsPrevious studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. These stresses come from a combination of ...Suppose that you want to perform a hypothesis test for a population mean. Assume that the variable under consideration has a symmetric nonnormal distribution and that the population standard deviation is unknown. Further ...Suppose that, in a hypothesis test, the null hypothesis is in fact false. a. Is it possible to make a Type I error? Explain your answer. b. Is it possible to make a Type II error? Explain your answer. Refer to Exercise 9.10. Explain what each of the following would mean. a. Type I error b. Type II error c. Correct decision Now suppose that the results of carrying out the hypothesis test lead to rejection of the null ...a. Rejection region. b. Nonrejection region. c. Critical value(s). d. Significance level. e. Construct a graph similar to that in Fig 9.2 on page 350 that depicts your results from parts (a)–(d). f. Identify the hypothesis ...
