The records of a medical clinic show x- 53 children with the defect, from a total of 50,000 children that were examined. If the 50,000 children were a random sample from the population of children represented by past records, what is the probab lity of observing a value of x equal to 53 or more? (Round your answer to four decimal places.) 03618 Would you say that the observ ton of x-53 children with genetic defects represents rare event? The observation is not rare because the probability is greater than 0.0s. The observation is rare because the probability is less than 0.05. You may need to use the appropriate appendix table or technology to answer this questionExplanation / Answer
From statistical software output of binomial probabilities, the required probabilities will be:
a) P(Fewer than 36) = 0.1181
b) P(More than 41) = 0.1991
c) P(More than 9 believes that recycling does not make the biggest difference)
= P(Less than 41)
= 0.6870
