Choose the correct example for positive correlation:a.Weight and incomeb.Price and demandc.The repayment period and EMId.Income and expenditure

To determine the correct example for positive correlation, we need to understand what positive correlation means. Positive correlation refers to a relationship between two variables where an increase in one variable is associated with an increase in the other variable.

Now let's analyze the given options:

a. Weight and income: This example does not necessarily demonstrate a positive correlation. While it is possible that individuals with higher incomes may have access to better food and exercise facilities, leading to lower weights, this relationship is not always true. Therefore, weight and income may not exhibit a strong positive correlation.

b. Price and demand: This example is a good candidate for positive correlation. As the price of a product increases, the demand for that product typically decreases. This inverse relationship suggests a negative correlation, not a positive one.

c. The repayment period and EMI: This example does not demonstrate a positive correlation. The repayment period and EMI (Equated Monthly Installment) are typically inversely related. As the repayment period increases, the EMI decreases, and vice versa.

d. Income and expenditure: This example is a strong candidate for positive correlation. As income increases, individuals tend to spend more on various goods and services. Therefore, income and expenditure exhibit a positive correlation.

Based on the analysis, the correct example for positive correlation is d. Income and expenditure.
