Answer

Explanation:

Step1: Calcular la suma de cada columna

Para la columna de "Placebo": $30 + 8=38$. Para la columna de "Luck potion": $23 + 5 = 28$.

Step2: Calcular las frecuencias relativas de columna para "Blocked the goal"

Para "Placebo": $\frac{30}{38}\approx 0.79$. Para "Luck potion": $\frac{23}{28}\approx 0.82$.

Step3: Calcular las frecuencias relativas de columna para "Did not block the goal"

Para "Placebo": $\frac{8}{38}\approx 0.21$. Para "Luck potion": $\frac{5}{28}\approx 0.18$.

Answer:

Placebo Luck potion
Blocked the goal 0.79 0.82
Did not block the goal 0.21 0.18
