<h3>Cómo construir un diagrama a partir de un enunciado</h3>
En esta pregunta debemos elaborar un diagrama de flujo, puesto que el enunciado muestra de manera evidente una clasificación de los viajeros según las ciudades de destino.
Nótese que se trata de un diagrama bastante simple, dado que no existe evidencia de jerarquización entre las ciudades mencionadas.
Tras una lectura cuidadosa del enunciado encontramos que de 25 estudiantes de cuarto grado "C" que decidieron irse de viaje, 10 viajaron a Paracas, 15 viajaron a Arequipa, 7 viajaron a los dos lugares citados y 3 viajaron a Chosica.
A continuación, presentamos el diagrama de flujo asociado a este caso en la imagen adjunta abajo.

Answer:
(1) The probability that the time to deliver a pizza is at least 32 minutes is 0.70.
(2a) The percentage of results more than 45 is 79.67%.
(2b) The percentage of results less than 85 is 91.77%.
(2c) The percentage of results are between 75 and 90 is 15.58%.
(2d) The percentage of results outside the healthy range 20 to 100 is 2.64%.
Step-by-step explanation:
(1)
Let <em>Y</em> = the time taken to deliver a pizza.
The random variable <em>Y</em> follows a Uniform distribution, U (20, 60).
The probability distribution function of a Uniform distribution is:
Compute the probability that the time to deliver a pizza is at least 32 minutes as follows:
Thus, the probability that the time to deliver a pizza is at least 32 minutes is 0.70.
(2)
Let <em>X</em> = results of a certain blood test.
It is provided that the random variable <em>X</em> follows a Normal distribution with parameters and
.
The probabilities of a Normal distribution are computed by converting the raw scores to <em>z</em>-scores.
The <em>z</em>-scores follows a Standard normal distribution, N (0, 1).
(a)
Compute the probability that the results are more than 45 as follows:
The percentage of results more than 45 is:
Thus, the percentage of results more than 45 is 79.67%.
(b)
Compute the probability that the results are less than 85 as follows:
The percentage of results less than 85 is:
Thus, the percentage of results less than 85 is 91.77%.
(c)
Compute the probability that the results are between 75 and 90 as follows:
The percentage of results are between 75 and 90 is:
Thus, the percentage of results are between 75 and 90 is 15.58%.
(d)
Compute the probability that the results are between 20 and 100 as follows:
Then the probability that the results outside the range 20 to 100 is: .
The percentage of results outside the range 20 to 100 is:
Thus, the percentage of results outside the healthy range 20 to 100 is 2.64%.
