4. Let X denote the forced vital capacity (FVC) in liters for a female college student. This is the amount of air that a student can force out of her lungs. Assume that the distribution of X is approximately M(u, o:). Suppose it is known that / = 3.4 liters. A volleyball coach claims that the FVC of volleyball players is greater than 3.4. She plans to test her claim using a random sample of size 9. a. Define the null and alternative hypotheses for her test. b. Define the test statistic and the decision rule for the test. C. Given the observed sample below, compute the test statistics and give your conclusion: 3.4 3.6 3.8 3.3 3.4 3.5 3.7 3.6 3.7 d. What is the approximate p-value of this test
