In: Statistics and Probability
The caffeine content of a cup of coffee in the cafeteria is a normally distributed random variable with μ = 130 mg and σ = 30 mg.
The caffeine content of a cup of coffee in the cafeteria is a normally distributed random variable with μ = 130 mg and σ = 30 mg.
-
- What is the probability that a randomly chosen cup of coffee will have more than 130 mg?
- Less than 100 mg?
- Between 90 mg and 150 mg?
- If the cup of coffee was the strongest 5% in caffeine content (hint: think about whether this would be above or below the mean), how many mgs of caffeine would it contain?
- If the cup of coffee was the weakest 10% in caffeine content (hint: think about whether this would be above or below the mean), how many mgs of caffeine would it contain?
