Fyedka had a dream about an important meeting he had at work. According to the activation-information model, Fyedka was

El gerente de un resort vacacional considera que las edades de los visitantes adultos pueden ser representadas mediante una distribución normal. El gerente llevó a cabo una encuesta a una muestra aleatoria de 765 visitantes y registró sus edades. Un resumen de las respuestas se presenta en la tabla de frecuencias, donde x representa la edad del visitante.

(a) Elabore un histograma de la distribución de edades.

(b) Escriba algunas frases para describir la distribución de edades de los visitantes adultos del resort.

(c) ¿Proporciona el histograma evidencia convincente de que las edades encuestadas provienen de una distribución normal? Justifique su respuesta.

Edad (años) Frecuencia

20≤x<30 160

30≤x<40 130

40≤x<50 100

50≤x<60 115

60≤x<70 125

70≤x<80 135

Answer:

Explanation:

a) Un histograma es, en esencia, un gráfico de barras de la información. En este caso, el histograma mostrará las edades en la parte inferior (eje x horizontal) y las alturas de cada barra corresponderán al número en ese rango de edad (frecuencia)... Consulte el archivo adjunto para el histograma

b) Una vez que tenga el histograma, describo la forma general.

¿Tiene forma de campana (con la barra más alta en el medio y disminuyendo a medida que te alejas)?

¿Es rectangular?

¿Es como una curva de campana inclinada?

Su forma da información sobre la naturaleza de los datos que puede ofrecer pistas sobre lo que parece la población.

Dado que tiene forma de una U estirada, se refiere a una relación no lineal entre dos variables, en particular, la edad depende de su frecuencia.

C. No, porque dado que la curva del histograma no tiene forma de campana, no puede ser una distribución normal.

Answer:

Approximately 66% of women who participated in the marathon finished with a time faster than Kathy's (rounded to the nearest whole number)

Explanation:

1. To analyze this correctly, let's go over the provided data:

The average finishing time for women = 259 minutes

Standard deviation of finishing time for women = 32 minutes

Kathy's finishing time = 272 minutes

2. To find the proportion of women who ran the marathon with times less than Kathy's, we will calculate the z-score for her finishing temperature as follows:

z-score = (272 - 259)/32

z-score = 13/32 = 0.41 (rounded to the nearest hundredth)

Using the z-table, we can now determine the proportion of women who completed the marathon in less time than Kathy:

p(z=0.41) = 0.6591

About 66% of women who completed the marathon had a quicker finishing time compared to Kathy's (rounded to the nearest whole)

Answer:

The Cerebellum is the brain region responsible for balance, coordination, and speech, among other functions, such as receiving signals from critical components of the central nervous system including the spinal cord.

Damage to this brain region may explain Kristi’s difficulties in maintaining her balance.

Magnetic Resonance Imaging (MRI):

MRI is a diagnostic tool used for identifying diseases, providing diagnoses, and evaluating treatment. It employs non-invasive techniques to create clear, three-dimensional images of internal organs, including the brain.

Neuroplasticity

This function of the nervous system refers to its capacity to adapt by reorganizing and creating nerve cells, compensating for injuries or illnesses.

Children typically exhibit a higher degree of neuroplasticity than adults. If Kristi is still quite young, she may recover with minimal or no treatments necessary.

Cheers.
