Expert Solution
Solution:
Question 1) If there is no correlation between two variables, what is the value of the correlation coefficient?
Correlation coefficient is always between -1 to +1.
If correlation coefficient = -1 then there is perfect negative and if it is +1 , then there is perfect positive correlation between two variables.
If correlation coefficient = 0 , then there is no or 0 correlation between two variables.
Thus correct option is: b. 0
Question 2) In a scatter diagram, on which axis is the dependent variable always recorded?
In a scatter diagram, the dependent variable always recorded on Y axis and independent variable is recorded on X axis,
Thus correct answer is: b. y axis
Question 3) What is the dependent and independent variable?
independent variable is the variable which does not depends on another variable or it does not have any effect of other variable.
whereas dependent variable is variables which is affected by another variable directly or indirectly.
Thus time does not depend on quantities produced whereas quantities produced depends on time consumed.
Thus
dependent variable is: quantities produced
and independent variable is: time.

What is/are true about the correlation between the two
variables?
I. It measures the strength of the linear relation between the
variables, as seen in the roundness/flatness of the scatterplot
between the two variables.
II. If the correlation equals 0, then there is no relation
between the two variables.
III. If the correlation is very high, then there is a strong
causal relation between the two variables.
a. l only
b. II only
c. I and III

Each of the following scenarios describes a correlation
between two variables. State whether the correlation is most likely
due to a coincidence, a common underlying cause, or a direct cause.
If there is an underlying cause, state what you think it is. If you
believe that one variable directly causes the other, suggest
possible physical causation.
