A study was conducted that measured the total brain volume (TBV) (in ) of patients that had schizophrenia and patients that are considered normal.Table #9.3.5 contains the TBV of the normal patients and table #9.3.6 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.

a.)State the random variables and the parameters in words.

b.)State the null and alternative hypotheses and the level of significance

c.)State and check the assumptions for the hypothesis test

d.)Find the sample statistic, test statistic, and p-value

e.)State the statistical conclusion (in terms of accepting or rejecting the null hypothesis)
