Test the hypothesis that sigma 1 greater than sigma 2 at the alpha equals 0.01 level of significance for the given sample data. Assume that the populations are normally distributed. Use the P-value approach. Population 1 Population 2 n 24 13 s 9.4 5.5 State the null and alternative hypotheses for this test. Upper H 0: sigma 1 ModifyingAbove p with caret 1 mu 1 sigma 1 equals equals greater than less than not equals sigma 2 ModifyingAbove p with caret 2 mu 2 sigma 2 Upper H 1: sigma 1 sigma 1 ModifyingAbove p with caret 1 mu 1 greater than less than greater than not equals equals sigma 2 sigma 2 ModifyingAbove p with caret 2 mu 2 Use technology to find the P-value for this test. The P-value is about nothing. (Round to three decimal places as needed.) Make a statement regarding the null hypothesis and draw a conclusion for this test. Since the P-value is â–¼ less than greater than the alpha equals 0.01 level of significance, â–¼ reject do not reject the null hypothesis. There â–¼ is is not sufficient evidence to conclude that the standard deviation of Population 1 is significantly greater than the standard deviation of Population 2 at the alpha equals 0.01 level of significance.
