Easy -1.8 This is a trivial recall question worth only 1 mark that tests whether students know the notation N(μ, σ²) means the second parameter is variance, not standard deviation. It requires only taking a square root of 0.35 and circling the correct answer from four options, with no problem-solving or application needed.
\(X \sim \text{N}(14, 0.35)\)
Find the standard deviation of \(X\), correct to two decimal places.
Circle your answer.
