color blindness appears in 2% of the people in a certain population. how large must a random sample be in order to be 99% certain that a color blind person is included in the sample?
X ~ Binomial(n = ?, p = 0.02) (assuming a 'large' population).
The smallest integer value of n such that is required.
Therefore find the smallest integer solution to . Trial and error is as good a technique as any.
Hint: I get an answer for n that's larger than 200 but smaller than 300 .......
