Answer 1

Option C, 1425

The following information is provided,
Significance Level, α = 0.02, Margin or Error, E = 5, σ = 81

The critical value for significance level, α = 0.02 is 2.33.

The following formula is used to compute the minimum sample size required to estimate the population mean μ within the required margin of error:
n >= (zc *σ/E)^2
n = (2.33 * 81/5)^2
n = 1424.76

Therefore, the sample size needed to satisfy the condition n >= 1424.76 and it must be an integer number, we conclude that the minimum required sample size is n = 1425
Ans : Sample size, n = 1425
