Tis believed that the sat scores for students entering two state universities may have different standard deviations. specifically, it is believed that the standard deviation at university a is greater than the standard deviation at university b. to test this using an alphaequals=0.05 level, a sample of 14 student sat scores from university a was selected and a sample of 8 sat scores from university b was selected. the following sample results were observed. university a university b x overbar equals=1104x overbar equals=1254 sequels=134 sequals=108 based on this information,
what is the critical value that will be used to test the hypothesis?
