1- (i) For populations scattered in a wide area, the preferred technique for sampling is cluster sampling. (ii) If the population can be divided into homogeneous subgroups, stratified random sampling is the best sampling method to use. (iii) If every k-th item in the population sequence is selected, you are using systematic random sampling. 2- i. If a population is not normally distributed, the sampling distribution of the sample means tends to approximate a normal distribution. ii. The Central Limit...
