What does a positive covariance between two variables indicate?Question 1Answera.Variables move in opposite directionsb.There is no relationship between variablesc.One variable is constantd.Variables move together in the same direction

The covariance between two variables is(a) Strictly positive(b) Strictly negative(c) Always 0(d) Either positive or negative or zero

If the values of two variables move in the same direction, then the correlation is said to be __________a.Non-linearb.Linearc.Positived.NegativeClear my choice

When cov(X,Y) = 0, what does it indicate? X and Y tend to move in same direction. X and Y are independent. X and Y tend to move in opposite directions. None of the above

The covariance between two random variables is -551351. What can be said about their relationship?Group of answer choicesThe variables must be independent of one another.The two variables have a very weak negative relationship.The two variables have a very strong negative relationship.The line of best fit between the two variables would be downward sloping.

Assertion (A) Broadly, there only two types of correlation i.e., positive and negative.Reason (R) The correlation is said to be positive when the variables move together in the same direction, the correlation is negative when they move in opposite directions.
