b) 6
c) 12
d) 7
 
If we conducted a hypothesis test to determine if there is a linear relationship between postnatal depression scores and antenatal depression scores then which of the following would constitute a Type 2 error

a) Decide that there is no relationship between the postnatal and antenatal depression scores when a significant relationship does exist.
 
b) Decide that there is a significant relationship between the postnatal and antenatal depression scores when there is not.
