TAILIEUCHUNG - Lecture Statistical techniques in business and economics (14/e): Chapter 10 - Lind, Marchal, Wathen

Chapter 10 - One-sample tests of hypothesis. In this chapter, the learning objectives are: Define a hypothesis and hypothesis testing, describe the five-step hypothesis-testing procedure, distinguish between a one-tailed and a two-tailed test of hypothesis, conduct a test of hypothesis about a population mean, conduct a test of hypothesis about a population proportion, | One-Sample Tests of Hypothesis Chapter 10 GOALS Define a hypothesis and hypothesis testing. Describe the five-step hypothesis-testing procedure. Distinguish between a one-tailed and a two-tailed test of hypothesis. Conduct a test of hypothesis about a population mean. Conduct a test of hypothesis about a population proportion. Define Type I and Type II errors. Compute the probability of a Type II error. Hypothesis and Hypothesis Testing HYPOTHESIS A statement about the value of a population parameter developed for the purpose of testing. HYPOTHESIS TESTING A procedure based on sample evidence and probability theory to determine whether the hypothesis is a reasonable statement. TEST STATISTIC A value, determined from sample information, used to determine whether to reject the null hypothesis. CRITICAL VALUE The dividing point between the region where the null hypothesis is rejected and the region where it is not rejected. Important Things to Remember about H0 and H1 H0: .
