Question

2c) what is the probability that a data value in a normal distribution is between a z - score of - 1.52 and a z - score of - 0.34? round your answer to the nearest tenth of a percent. # choice a. 27.3% b. 29.3% c. 30.3% d. 28.3%

Explanation:

Step1: Encontrar la probabilidad para \(z = - 1.52\)

Usando la tabla de la distribución normal estándar, \(P(Z < - 1.52)=0.0643\)

Step2: Encontrar la probabilidad para \(z=-0.34\)

Usando la tabla de la distribución normal estándar, \(P(Z < - 0.34)=0.3669\)

Step3: Calcular la probabilidad entre los dos \(z -\)scores

\(P(-1.52<Z < - 0.34)=P(Z < - 0.34)-P(Z < - 1.52)\)
\(P(-1.52<Z < - 0.34)=0.3669 - 0.0643\)
\(P(-1.52<Z < - 0.34)=0.3026\)

Answer:

C. \(30.3\%\)
