Answer

Explanation:

Paso 1: Calcular la distancia promedio del coche sin peso

Sumamos las distancias de los tres ensayos del coche sin peso: $75 + 72+73 = 220$ cm. Luego dividimos por el número de ensayos (3). La fórmula para el promedio $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, donde $n = 3$ y $x_{1}=75$, $x_{2}=72$, $x_{3}=73$. Entonces $\bar{x}=\frac{220}{3}\approx73.33$ cm.

Paso 2: Calcular la distancia promedio del coche pesado

Sumamos las distancias de los tres ensayos del coche pesado: $61+52 + 55=168$ cm. Dividimos por el número de ensayos (3). Usando la misma fórmula para el promedio, con $n = 3$ y $x_{1}=61$, $x_{2}=52$, $x_{3}=55$, tenemos $\bar{x}=\frac{168}{3}=56$ cm.

Respuesta:

Distancia promedio coche sin peso: $73.33$ cm Distancia promedio coche pesado: $56$ cm ¿El coche más pesado recorrió más distancia? NO ¿La hipótesis fue aceptada? RECHAZADA ¿Cómo afectó la altura de la rampa la distancia que rodó el coche? A medida que aumentó la altura de la rampa, la distancia que rodó el coche aumentó.
