The given statement about the correlation between two variables is; False

<h3>Pearson's correlation coefficient </h3>

Pearson's correlation coefficient is the measure of linear correlation between two sets of data.

Pearson's r is always between the values of -1 and +1.

In that range, -1 denotes a perfect negative while +1 denotes a perfect positive relationship and 0 denotes the perfect absence of a relationship.

Finally, Pearson's r is symmetric and as such the correlation between two variables x and y must be the same as the correlation between y and x.

Thus, if the correlation between x and y is 0.8, then the correlation between y and x must be also 0.8 and not -0.8 as the question states.

Ronch [10]

A profit maximizing monopoly's total revenue is equal to; (P₃ - P₀) * Q₂

<h3>How to interpret Monopoly Curve?</h3>

Pure monopoly can raise the market price indefinitely due to the fact that the market structure is characterized by a single seller or manufacturer, selling a particular product in the market.

In a pure monopoly market, the seller faces no competition, as he is the sole seller of goods with no close substitute. He enjoys the power of setting the price for his goods. This in-turn leads to the customers being at the mercy of the seller.

In the attached image which shows the cost and revenue structure for a Monopoly Firm Cost And Revenue($) and we see that, curve A is the demand curve, Curve B is the marginal revenue curve, curve C is the marginal cost curve and curve D is the average total cost curve.

Thus, a profit maximizing monopoly's total revenue is equal to;

(P₃ - P₀) * Q₂
