. A study was conducted that measured the total brain volume (TBV) (in mm³) of patients that had schizophrenia and patients that are considered normal.Table #3.1 contains the TBV of the normal patients and table #3.1 contains the TBV of schizophrenia patients ("SOCR data oct2009," 2013). Is there enough evidence to show that the patients with schizophrenia have less TBV on average than a patient that is considered normal? Test at the 10% level.

Step 1: State the question

Step 2: Identify the information

1. State the random variables and parameters in words

1. State the null and alternative hypotheses and level of significance

1. Determine the type of test this is, then state and check the assumptions for this type of test

Step 3: Perform calculations

1. Find the sample statistics

1. Find the test statistic

1. Find the p-value

1. State the conclusion (compare p and alpha and decide to reject H_o or fail to reject H_o)

Step 4. Interpret (answer the original question in a complete sentence)
