Extracted text: The Centers for Disease Control and Prevention reported that 20% of all preschool children lack required immunizations. A random sample of 18 preschool children will be selected. Let X = the number of preschool children without required immunizations in a random sample of 18. Question 8 Subquestions 8.a Think of all the reasonable outcomes of X. How many possible outcomes does X have? Too many to list 18 19 unknown 8.b What is the probability that exactly five preschool children will lack immunizations in a random sample of 18? P(X = 5) = 0.1507 P(X = 5) = 0.0000176 P(X = 5) = 0.000088


Extracted text: 8.c What is the probability that at least two of the preschool children will lack immunizations in a random sample of 18? P(X > 2) = 0.9189 P(X > 2) = 0.7287 P(X > 2) = 0.7467 P(X > 2) = 0.9009 8.d How many preschool children in the random sample of 18 would you expect to lack immunizations? X = 3 preschool children X = 3.6 preschool children X = 4 preschool children O p = 3 preschool children O H = 3.6 preschool children O H = 4 preschool children
