Researchers dropped 200 identical wallets on sidewalks near a large university. Each wallet contained the name and address of th

e owner and either a photograph of a baby, a photograph of a puppy, a photograph of a young family, a photograph of an older couple, or no photograph. The researchers hypothesized that the type of photograph left in the wallet would influence the rate of return. The wallets with a photograph of the baby and the wallets with a photograph of the puppy were left early in the morning, the wallets with a photograph of the young family were left in the afternoon, and the wallets with either no photograph or a photograph of an older couple were left in the evening. Eighty-four of the 200 wallets (42%) were eventually mailed back to the owner, as shown below.

The manager of a vacation resort believes the ages of adult visitors to the resort can be modeled by a normal distribution
Fittoniya [250]

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.

In the third sentence of the first paragraph, the narrator’s description of Mrs. De Ropp as “those three-fifths of the world tha
pickupchik [329]
In the excerpt from ‘Sredni Vashtar’ by Saki (Hector Hugh Munro, 1870 - 1916), it is indicated that the protagonist, Conradin, perceives the world as divided into two sections. His cousin, Mrs. De Ropp, whom he harbors a strong dislike for, is part of the larger segment of reality (making up three-fifth). This portion is deemed necessary, as it ensures the practical aspects surrounding Conradin work correctly (such as acquiring food and clean clothes). However, it is also labeled as disagreeable due to its imposition of rules and control over Conradin, similar to how Mrs. De Ropp behaves. Furthermore, this segment is described as real because it is tangible, contrasting with the imaginary realm Conradin relates to.
