Carly Long · Answer 1

(a) GDP is a dependent variable and aggregate net investment is a independent variable. There is a positive relationship between the variables which means that an increase in the net investment will lead to increase GDP.

(b) There is a negative relationship between the variables which means that as the supply of wheat increases, as a result price of wheat falls. So, as the number of acres of wheat planted in a season increases as a result price of wheat decline.

(c) There is a negative relationship between the variables which means that an increase in the interest rate in an economy will lead to increase the cost of borrowings and hence, net investment falls.

(d) There is a negative relationship between the variables because of the law of demand. It states that an increase in the price of a commodity will lead to reduce the quantity demanded for that commodity.

(e) There is no relationship between these variables. Both the variables are totally uncorrelated.
