An experiment was carried out where the level of dietary cholesterol (measured in milligrams per 1000 calories) was measured for two different groups of individuals, those who do not consume fish, and those who consume a high amount of fish. The information is summarized below: Sample Size Mean Variance No fish consumption (Population 1) 15 158 58 High fish consumption (Population 2) 12 146 67 . Suppose a test for the equality of the variances of the level of dietary cholesterol in the two groups of individuals is carried out at a 10% level of significance. The critical values are 0.39 and 2.74. The value of the test statistic and the decision that will be made are respectively, (correct to 3 decimal places) and • Sunross the null hypothesis for the test carried out above is not reiected. If a hypothesis test is carried out at a 10% level of significance to determine if the consumption of fish reduces the average amount of dietary cholesterol in an individual, the value of the test statistic, correct to 2 decimal places. is • the critical value of correct to 2 decimal places
