TRUE OR FALSE: 1. The sampling distribution of (X-bar) is always a normal distribution according to the Central limit theorem. 4. If the sampled population is a normal distribution, then the sampling distribution of   (X-bar is normal only for a large enough sample size. 5. If p=.8 and n=50, then we can conclude that the sampling distribution of the proportions is approximately a normal distribution. 8. Assuming the same level of significancea, as the sample size increases, the critical t-value...
