Challenge Problems
Push your limits with challenges.
Question 1
A researcher finds that in a population of 1000 people, 40% are left-handed. If we sample 100 individuals, use the normal approximation to find the probability that at least 45 are left-handed.
💡 Hint: Start with np and npq calculations.
Question 2
You conduct an experiment with 50 trials where the probability of success is 0.3. Use the normal approximation to find the probability of getting between 10 and 20 successes.
💡 Hint: Don't forget to adjust your limits!
