类型：online_judge
Given a numeric array, significance level, power, and effect size to detect, calculate the required sample size using a two-sample z-test.
Use the following formula for calculations:
Input:
numeric_array: Numeric array
sig_level: Significance level (α)
power: Power of test (1 - β)
effect_size: Effect size to detect
Output: Required sample size
Example Input:
numeric_array = [1.2, 2.4, 3.5]
sig_level = 0.05
power = 0.8
effect_size = 0.5
Example Output:
sample_size = 64
