Question

Decide whether the following statements are True or False.

a) Probability is a measure of the likelihood of a random phenomenon or chance behavior.

b) In a binomial experiment that satisfies np(1-p) 10, then we can approximate it with a normal distribution.

c) if a random variable X is normally distributed, then the distribution of the sample mean, x, is also normally distributed.

d) the law of large numbers says that as additional observations are added, the difference between the sample mean, x, and the population mean goes to zero.

e) the central limit theorem says that regardless of the shape of the population, the sampling distribution of x becomes approximately normal as the sample size n is greater or equal to 30.

f) the outlier can be exactly at the minimum

g) in a relative frequency distribution, the relative frequencies should add up to one.

h) the 75th percentile is also known as the third quartile.

i) if a population is normal, then the distribution of the sample mean will be uniform.
