A study was conducted to determine if the performance of a certain type of surgery on young horses had any effect on certain kinds of blood cell types in the animal. Fluid samples were taken from each of six foals an hour after the operation. Suppose that the data on WBC leukocytes follow the normal distribution. One sample Chi-squared test for variance data: wbc X-squared = 3.5321, df = 5, p-value = 0.3815 alternaative hypothesis: true variance is less than 4 Question: Is there evidence to say that the variance of WBC leukocytes is less than 4? State the conclusion based from the results of the test. Choices: - There is no sufficient evidence that the variance of WBC leukocytes is less than 4. - There is a sufficient evidence that the variance of WBC leukocytes is less than 4.
