of the last 320 flights to arrive at newton airport, 8 were late. considering this data, how many of the next 840 flights would you expect to arrive late? flights

Answer

Explanation:

Step1: Calcular la proporción de vuelos retrasados

La proporción de vuelos retrasados en los 320 vuelos anteriores es $\frac{8}{320}=\frac{1}{40}$.

Step2: Calcular el número esperado de vuelos retrasados

Multiplicamos la proporción por el número de vuelos futuros. Así, para 840 vuelos, el número esperado de vuelos retrasados es $\frac{1}{40}\times840 = 21$.

Answer:

21
