Two different analytical tests can be used to determine the impurity level in steel alloys. Eight specimens are tested using both procedures, and the results are shown in the following tabulation. Is there sufficient evidence to conclude that both tests give the same mean impurity level, using a = 0.01? Round numeric answer to 2 decimal places. Specimen Test 1 Test 2 1.2 1.4 2 1.3 1.7 3 1.5 1.5 4 1.4 1.3 5 1.7 2.0 6 1.8 2.1 7 1.4 1.7 8 1.3 1.6 There is sufficient evidence to conclude that both tests give the same mean impurity level since the test statistic = 2.98 is not v in the rejection region
