8. For a continuous distribution, P(X ≤ 100) is greater than P(X<100).

9. A continuous variable may not be Normally distributed.

10. The mean of a standard normal distribution is not equal to 1.

11. If the sample size is 1000, we can safely use the normal approximation to binomial even for small p.

12. For a binomial probability experiment, if p is 0.1 and n is only 150, we cannot use the normal approximation to the binomial distribution without continuity correction.
