An Izod impact test was performed on 17 specimens of PVC pipe, the sample standard deviation was 0.25. (a) Test the hypothesis that o = 0.10 against an alternative specifying that o 0.10, using a = 0.01. State any necessary assumptions about the underlying distribution of the data. Find x. Round your answer to two decimal places (e.g. 98.76). Xó = Is it possible to reject Ho hypothesis at the 0.01 level of significance? O Yes. O No.
(b) Find the P-value for this test. value < 0.005 value < 0.01 value < 0.05 O P value < 0.1 OP O P OP - (c) Construct a a 99% two-sided confidence interval for o to answer the question in part (a). Round your answers to two decimal places (e.g. 98.76). <o<
