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 #1 contains the TBV of the normal patients and Table #2 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.

 (vii)  Determine test statistic:

Enter value in decimal form rounded to nearest ten-thousandth.  Examples of correctly entered answers:

0.0104      3.0370        16.5000        110.0819

 

 (viii)  Using tables, calculator, or spreadsheet:  Determine and enter p-value corresponding to test statistic.

Enter value in decimal form rounded to nearest ten-thousandth.  Examples of correctly entered answers:

0.0001     0.0021     0.0305     0.6004      0.8143     1.0000

 

 (ix)  Comparing p-value and α value, which is the correct decision to make for this hypothesis test? 

A.  Reject Ho

B.  Fail to reject Ho

C.  Accept Ho

D.  Accept HA

Enter letter corresponding to correct answer.
