compare the probability that an adult has side effects with the probability
that a child has side effects. draw a conclusion based on your results.

Answer 1

Of the 50 adults tested:

- 6 had side effects

- 44 did not have side effects

Therefore, the probability that an adult has side effects is 6/50 = 0.12

Of the 50 children tested:

- 20 had side effects

- 30 did not have side effects

Therefore, the probability that a child has side effects is 20/50 = 0.40

Since 0.40 is greater than 0.12, the probability that a child has side effects is greater than the probability that an adult has side effects.

Conclusion: Based on these results, children were more likely to experience side effects from the drug than adults.
