Challenge Problems
Push your limits with advanced challenges
A civil engineer measures the thickness of concrete slabs at a construction site, finding that values follow a normal distribution with a mean of 6 inches and a standard deviation of 0.5 inches. What percentage of slabs will be thicker than 6.5 inches?
💡 Hint: Don't forget to apply the Z-score and look it up on a standard normal distribution table!
In a measuring experiment, a sensor's readings produce standard deviations that consistently result in a systematic error shifting toward higher values. How can neglecting this uncertainty affect structural assessments?
💡 Hint: Reflect on what marks 'true' measurements versus misleading readings.
