Use normal approximations to binomial models - calculation checkpoint
For a school canteen binomial variable with \(n=90\) and \(p=0.35\), use a normal approximation with continuity correction to standardise \(P(X\le 36)\). Find the corrected \(z\)-value. Enter the requested value and choose the interpretation that matches the result.
Worked practice: result and interpretation
Calculate the requested result first, then choose the interpretation that follows from it.
