**ANSWERS: STATISTICS MCQS**

1. (B) 5

2. (D) 1.2

3. (A) lognormal

4. (A) 4

5. (C) F test (Find the solutions below)

**SOLUTIONS: STATISTICS MCQS**

**1.** Here total numbers are 6. So,

**2.** The probability of an event is always between 0 and 1 (including 0 and 1). So, 1.2 cannot be the probability of an event.

**3.** A lognormal distribution is a probability distribution of a random variable whose logarithm is normally distributed. So, if X is lognormal then Y=ln(X) is normal. Similarly, if Y is normal then X=e^{Y} is lognormal.

**4.** There are 4 numbers in total. So, by using the formula for calculating geometric mean, we have
