1. If a random variable X takes the value 1,2,3,4 suchthat 2P(X = 1) = 3P(X = 2) = P(X = 3) = 5P(X = 4).Find the probability distribution of X.
Suppose you are a lawyer representing a Hispanic individual in a criminal trial. Twelve jurors are randomly selected by the state from a population that you know to be 40% Hispanic. 4.8 JURORS ARE EXPECTED TO BE HISPANIC. The select process produces a jury with 3 Hispanic individuals, meaning that 25% of the jury is Hispanic. Using the binomial distribution we find that the probability that 3 or fewer jurors would be Hispanic is 0.2253. Create a graph of the distribution with the area corresponding to the previous information. Use Statistics to make an argument to the court on behalf of your client. Explain why random sampling in this situation of juror selection relates the expected sample proportion to the population proportion.Compare the expected value to the actual sample proportion.
Renee and Thomas live at the beach and collect seashells. The number of shells Renee collects on any given day, R, is approximately Normal with a mean of 58.2 shells and a standard deviation of 12.8 shells. The number of shells Thomas collects on any given day, T, is approximately Normal with a mean of 47.9 shells and a standard deviation of 11.5 shells. Assume the two random variables are independent of each other. What is the probability that on a randomly selected day the total number of shells collected by Renee and Thomas is 120 or more? 0.002 0.209 0.284 0.791
