Answer:

Para estimar cuántas personas tienen gripe en la población total, podemos usar una proporción basada en la muestra proporcionada.

Dado que 20 personas de una muestra de 250 tienen gripe, podemos establecer la proporción de la siguiente manera:

20 personas de 250 = x personas de 225,000

Resolviendo para x:

x = (20 * 225,000) / 250

x = 4,500,000 / 250

x = 18,000

Por lo tanto, se estima que 18,000 personas tienen gripe en la población total.
