Task 7 You can do it! Consider the heights of 5 learners. Suppose you are interested in estimating the average height of the learners by getting estimates based on the sample average height of two learners selected at random with replacement. The learners have equal chance of being selected Learner 2 3 Height (in meter) 164 1.58 1.58 1.33 1.60 5 Find the following (2pts each): 1. list of all possible random samples. 2. the population mean. 3. the population variance and standard deviation 4. the expected value 5. the standard error
