To solve for the sample size, we need to use the appropriate formulas based on the given information.
1. For N = 293 with a 96% confidence level, we can use the formula:
n = (Z * σ / E)²
where n is the sample size, Z is the Z-score corresponding to the confidence level, σ is the population standard deviation (if known), and E is the desired margin of error.
2. For N = 408 with a 0.002 significance level, we can use the formula:
n = (Z * σ / E)²
where n is the sample size, Z is the Z-score corresponding to the significance level, σ is the population standard deviation (if known), and E is the desired margin of error.
3. For N = 530 with a 0.953 level of confidence, we can use the formula:
n = (Z * σ / E)²
where n is the sample size, Z is the Z-score corresponding to the confidence level, σ is the population standard deviation (if known), and E is the desired margin of error.
To calculate the sample size, we need to know the Z-score and the desired margin of error. Without this information, it is not possible to determine the sample size accurately.
If you have the Z-score and margin of error, please provide them, and I'll be happy to help you calculate the sample size.
