kamden is a mind - reading alien. he had each friend draw and look at a card, then he guessed whether the card had a star on it. the two - way frequency table below shows data on guess and true status of the cards the friends drew. complete the following two - way table of column relative frequencies. (if necessary, round your answers to the nearest hundredth.) card had a star card didnt have a star kamden guessed a star 4 1 kamden guessed not a star 2 752 column total 1.00 1.00

Answer

Explanation:

Step1: Calcular la suma de cada columna

Para la columna "Tarjeta tenía una estrella": $4 + 2=6$. Para la columna "Tarjeta no tenía una estrella": $1+752 = 753$.

Step2: Calcular las frecuencias relativas de columna

Para la celda donde la tarjeta tenía una estrella y Kamden adivinó una estrella: $\frac{4}{6}\approx0.67$. Para la celda donde la tarjeta tenía una estrella y Kamden adivinó no una estrella: $\frac{2}{6}\approx0.33$. Para la celda donde la tarjeta no tenía una estrella y Kamden adivinó una estrella: $\frac{1}{753}\approx0.00$. Para la celda donde la tarjeta no tenía una estrella y Kamden adivinó no una estrella: $\frac{752}{753}\approx1.00$.

Answer:

Para la columna "Tarjeta tenía una estrella": 0.67, 0.33. Para la columna "Tarjeta no tenía una estrella": 0.00, 1.00.
