Central Limit Theorem Problem Index
A Central Limit Theorem word problem will most likely contain the phrase “assume the variable is normally distributed”, or one like it. You will be given:
- A population (i.e. 29-year-old males, seniors between 72 and 76, all registered vehicles, all cat owners)
- An average (i.e. 125 pounds, 24 hours, 15 years, $15.74)
- A standard deviation (i.e. 14.4lbs, 3 hours, 120 months, $196.42)
- A sample size (i.e. 15 males, 10 seniors, 79 cars, 100 households)
- I want to find the probability that the mean is greater than a certain number
- I want to find the probability that the mean is less than a certain number
- I want to find the probability that the mean is between a certain set of numbers either side of the mean
