3119A (Read-Cnly] Word The breaking strength of a fabric types A and B has been tested 4 times and found A 4.2,4.5, 3.8, 5.3 psi. B 53, 56, 60, 6.0 (A competing new fabric) Test the claim saying average strength must be the same. Use X values with Cl, use Z/t values and use p values. State the conclusion with p values. Show calculations Answer! Question 4. A random experiment can result in one of the outcomes (a, b, c, d), with respective proba- bilities of 0.2, 0.2, 0.5, 0.1. Let A denote the event (a, b), B the event (b, c, d), and C the event (d). 1) Find P(A U C), 2) P(A intersection B) Answer Question 5 Each sample of water has a 10% chance of containing a particular organic pollutant. As- sume that the samples are independent with regard to the presence of the pollutant. Find the probability that in the next 25 samples, exactly 3 contain the pollutant.
