Challenge Problems
Push your limits with challenges.
Question 1
Given a normally distributed set with a mean of 100 and a standard deviation of 15, calculate the z-score for a value of 130.
💡 Hint: Z-scores can help you understand how far away from the mean a value is.
Question 2
If a structural component follows a normal distribution with a mean load of 5000 N and a standard deviation of 200 N, what is the likelihood it will fail if it can only support loads of 5300 N or less?
💡 Hint: Think about what it means for a value to be above the mean.
