Answer: 240
Formula:
n = [(z-value * sd)/E]^2
where n = sample size,
z-value will be 2.58 using a z-table to represent the 99% confidence interval
sd(standard deviation) = 3
E = 0.5
Substituting the parameters into the formula n = [(z-value * sd)/E]^2, we have,
n = [(2.58 ×3) ÷ 0.5]²
n = 239.63 approximately 240.
