42. En un conjunto de datos, se dice que un dato es atíico cuando es menor que \( Q_{1}-\frac{3}{2} R \) o mayor que \( Q_{3}+\frac{3}{2} R \), tal que \( Q_{1} \) es el primer cuartil de la distribución, \( Q_{3} \) es el tercer cuartily \( R \) es el rango intercuartilico. Considera un conjunto de datos con primer cuartil 20 y tercer cuartil 40 . Si los mayores datos de la distribución son \( 60,65,72 \) y 78, ¿cuántos de ellos son datos atípicos? A) 1 B) 2 C) 3 D) 4
