True or False:1. The central limit theorem only works when the population comesfrom a normal distribution.2. When the population is normally distributed, the sample size neednot be large (i.e. n>30) for the sampling distribution of X to benormally distributed.3. SRSWOR is a sample from an infinite population.4. SRSWR is a sample from a finite population.5. The t-distribution approaches the z-distribution as you decrease thedegrees of freedom.
