Survey your classmates about the number of siblings they have and the length of the last conversation they had with their mother. Identify the two random variables of interest and list their possible values a. Use a computer (or random number table) and generate a random sample of 100 observations drawn from the discrete probability population P(x) _ 5 – x/10 for x _ 1, 2, 3, 4 List the resulting sample.
