=== Assistant: 計算結果出來了!這次是 1000 個新生兒 → 600 男 vs 400 女 的情境。 === 計算結果出來了!這次是 1000 個新生兒 → 600 男 vs 400 女 的情境。 * 精確二尾 p 值:≈ 2.73 × 10⁻¹⁰ * 常態近似(不含連續性校正):≈ 2.54 × 10⁻¹⁰ * 常態近似(含連續性校正):≈ 3.12 × 10⁻¹⁰ ✅ 解讀: 這個 p 值極小,遠小於 0.05(甚至比 10⁻⁹ 還小),代表觀察到的「600 vs 400」幾乎不可能只是隨機誤差。 因此我們會強烈拒絕虛無假設 H0H_0H0,推論「男嬰出生率顯著高於 0.5」。 要不要我也幫你算算「560 vs 440」的例子,看看它落在「520 vs 480」和「600 vs 400」之間的情況?
