A viral infection is spread by contact with an infected person. Suppose that an infected person has contact with 15 healthy people, let X denote the number of people (out of these 15} who are infected. By \"infected" we mean that the person develops symptoms of the infection. Based on previous research, the infection rate is 25%. Which distribution would you use to model this event? 0 Binomial (15, 0.25) 0 Normal (0.25, 15) O Binomial (25, 0.15} 0 Normal (15, 0.25) What is the probability 5 or fewer (of the 15) become infected? 0 0.3385 0 0.3516 0 3.75 0 0.6243 Using the cutoff rule for the Scientic Method, how man);r successes would be needed to conclude the infection rate is greater than 25%? Choose the corresponding sample space. 0 {0.1} O {0. 1, 2} O {0.1, 2. 3, 4.5, 6} O {7. 8, 9,10,11,12.13,14,15}
