Confidence
A survey of 100 tomato plants out of a population of 5000 found an average height of 10 \(\pm\)1 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 \(\pm\)2 inches
Proportional to \(\frac{1}{d^2}\) -
Required confidence level increased to 99%
(1 - confidence) is proportional to \( \frac{1}{n}\)
