question:Which of the following statement(s) about “correlation” is/are false? (i) The more closely two variables follow the same increasing trend, the stronger the correlation. (ii) In a positive correlation, two variables tend to increase (or decrease) in the same direction. (iii) In a negative correlation, two variables tend to increase (or decrease) in the opposite directions. (iv) A positive correlation (statistically significant, P-value < 0.05) indicates a “cause and effect” relationship. A. (i) and (iii) B. (i) only C. (iv) only D. None of them
answer:C. Statement (iv) is false. A positive correlation between two variables indicates that they tend to increase or decrease together, but it does not necessarily mean that one variable causes the other. A correlation does not imply a causal relationship, and it is important to establish causality through other research methods.
question:Car A costs 30% more than Car B. Car C costs 25% less than Car A. Which car is cheapest? A. Cannot be determined from the information given B. Car B C. Car C D. Car A
answer:To determine which car is cheapest, we need to compare their prices. Let the price of Car B be x. Car A costs 30% more than Car B, so its price is: Price of Car A = x + 0.3x = 1.3x Car C costs 25% less than Car A, so its price is: Price of Car C = 0.75 × (Price of Car A) = 0.75 × 1.3x = 0.975x To compare prices, we can simplify the expressions: - Price of Car B = x - Price of Car A = 1.3x - Price of Car C = 0.975x Since x > 0, we can rank the prices as: Price of Car B < Price of Car C < Price of Car A Therefore, Car C is the cheapest option. The answer is (C).
