Sample TS = 2.52 4.(b) The sample mean is within the 99% confidence limits. 5. Using the data in the Example on Text p. 2501 (a) Calculate the 99% confidence limits of the putative population mean. Is the sample mean within the confidence limits of the population mean? (b) Test the hypotheses at the α = 0.005 level of significance. (c) Though the given values of sample mean, standard deviation and sample number justify rejection of the null hypothesis at the 0.01 level, they do not justify rejection at the 0.005 level. How many more samples would be needed to justify rejection at this level? Answers: 5.(a) The sample mean is within the 99% confidence limits. 5.(b) Low Tail TS = 4.60. Sample TS = 4.12 5.(c) One more sample measurement. Examples (do the problems, not the examples) Example for Problem 4 Example for Problem 5...
