Answer to relevant QuestionsGiven the probability function R(x) _ 0.2 , for x _ 0, 1, 2, 3, 4 , find the mean and standard deviation. 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. (Use the computer ...A die is rolled 20 times, and the number of “fives” that occur is reported as being the random variable. Explain why x is a binomial random variable. Demonstrates calculating a binomial probability along with a visual interpretation. Suppose that you are in a class of 30 students and it is assumed that approximately 11% of the population is left-handed. Inputting and p ...
