An Izod impact test was performed on 23 specimens of PVC pipe, the sample standard deviation was 0.25. (a) Test the hypothesis that a = 0.10 against an alternative specifying that a 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). Xô 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. OP-value < 0.005 OP-value < 0.01 OP-value < 0.05 OP-value < 0.1 (c) onst ta a 99% two-sided confidence interval for a to answer the question in part (a). Round your answers to two decimal places (e.g. 98.76). sosi
