Confidence
A survey of 100 tomato plants out of a population of 5000 found an average height of 10 \pm1 inches at a 95% confidence level.
How many samples would be required for the following scenarios, with all other parameters held constant?
-
Total population increased to 10000
No change -
Tolerance of estimate increased to \pm2 inches
Proportional to \frac{1}{d^2} -
Required confidence level increased to 99%
(1 - confidence) is proportional to \frac{1}{n}
