1. Multiple Choice: If the probability of an event occurring is 0.2, what is the probability of the event not occurring? a) 0.2 b) 0.8 c) 0.5 d) 0.1 Correct Answer: b) 0.8 Rationale: The probability of an event not occurring is 1 minus the probability of the event occurring, hence 1 - 0.2 = 0.8. 2. True/False: The Central Limit Theorem states that the sampling distribution of the sample means approaches a normal distribution as the sample size gets larger. Answer: True Rationale: The Central Limit Theorem indeed states that, given a sufficiently large sample size, the sampling distribution of the sample mean will be approximately normally distributed.
