Answer 1

Answers may vary. Possible answer
Sources of random error: 
women may not know their weight exactly
there may have been weight gain or loss since the last time they weighed themselves
the scales they used to weigh themselves may not be accurate, this is random error as some scales used may read too high while others may read too low
Systematic error: 
women perceiving themselves to be overweight may report their weight as lower than it actually is
