State the criteria that must be met for an experiment to be a binomial experiment.
Step 1 of 5) State the criteria that must be met for an experiment to be a binomial experiment. Testing Hypotheses Regarding Two Population Standard Deviations Problem In the Spacelab Life Sciences 2 payload, 14 male rats were sent to space. Upon their return, the red blood cell mass (in milliliters) of the rats was determined. A control group of 14 male rats was held under the same conditions (except for spaceflight) as the space rats, and their red blood cell mass was likewise determined when the space rats returned. The data in Table 5 were obtained. Is the standard deviation of the red blood cell mass in the flight animals different from the standard deviation of the red blood cell mass in the control animals at the a = 0.05 level of significance Approach Follow Steps 1 through 5 on pages 561–562. Solution We verified that the data are normally distributed in Example 1 from Section 11.3. Step 1 We want to know whether the standard deviation of the red blood cell mass in the flight animals is different from the standard deviation of the red blood cell mass in the control animals.
