An Izod impact test was performed on 15 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 Xo Round your answer to two decimal places (e.g. 98.76). x = i 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
