S-adenosyl methionine (SAM-e) is a naturally occurring compound in human cells that is thought to have an effect on depression symptoms. Suppose that a researcher is interested in testing SAM-e on patients who are struggling with Alzheimer's. She obtains a sample of n = 20 patients and asks each person to take the suggested dosage each day for 4 weeks. At the end of the 4-week period, each individual takes the Beck Depression Inventory (BDI), which is a 21-item, multiplechoice self-report inventory for measuring the severity of depression. The scores from the sample produced a mean of M = 24.4 with a standard deviation of s = 6.02. In the general population of Alzheimer's patients, the standardized test is known to have a population mean of p = 27.2. Because there are no previous studies using SAMe with this population, the researcher doesn't know how it will affect these patients; therefore, she uses a twotailed singlesample t test to test the hypothesis. From the following, select the correct null and alternative hypotheses for this study: 0 Ha: pSAMe s 27.2; H': \"AM, > 27.2 C) H\": pSAm = 27.2; H': pgAM_e at 27.2 0 H\": \"SAM, 2 27.2; H': pgAM_e
