The Minnesota Multiphasic Personality Inventory (MMPI-2) has one scale that measures paranoia (a mistaken belief that others are out to get you). The population mean on the paranoia scale is 50.

Suppose 24 police officers filled out the inventory, producing a mean of 54.3. Write interpretations of these t-test values.

a. t = 2.10

b. t = 2.05
