please will give 5 stars and amazing feedback! TRUE OR FALSE AND
WHY???
Homework Answers
Ans:
d)True
t=b1/sb1
t=10/2
t=5
e)True
Slope coefficient=10
So,one unit change in X will cause 10 units change in Y on average.
f)
False
Neither regression nor correlation analyses can be interpreted as establishing cause-and-effect relationships. They can indicate only how or to what extent variables are associated with each other.
