We can use the formula for standard deviation, which is: s = sqrt( Σ(X - M)^2 / n) We know that Σ(X - M)² = 235, which can be simplified as: Σ(X - M)^2 = ² * n * s^2 Plugging this back into the formula for standard deviation, we get: s = sqrt( ² * n * s^2 / n) s = sqrt( ² * s^2 ) s = s * sqrt(²) Dividing both sides by sqrt(²), we get: s = 235 / sqrt(² * n) Plugging in n = 29, we get: s = 235 / sqrt(² * 29) To solve for s, we need to know the value of ². None of the answer choices provide this value, so we cannot determine s.
