Answer:

Indeed, the business journal has accurately interpreted the probability; since 3 out of 5 randomly chosen internet users are likely to use the mobile payment app, this indicates a probability of 3/5 or 0.6. This aligns perfectly with what the business journal has reported.

Explanation:

The likelihood that internet users in the United States will utilize a mobile payment application stands at 0.60.

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.

How did some students and tutors find shortcuts to learning? How did the Chinese government react to these shortcuts?
kotykmax [209]

According to an alternative source, this question pertains to the text "The Chinese Civil Service Exam System” authored by Ichisada Miyazaki.

This text reveals that the civil service exams in China originated almost fourteen centuries ago, making it one of the oldest examination systems globally.

The purpose of this system was to identify the most talented young men in China for governmental roles, providing them with the necessary education. However, this process was lengthy and arduous, prompting many students and teachers to create effective shortcuts for exam preparation. For instance, rapid study techniques were developed, including compiled answer collections for exams.

Such methods were known to the Chinese authorities, who condemned them vehemently. Students utilizing these shortcuts faced failure, and the government frequently banned the publication of such resources. However, the business of producing these materials was thriving, leading to the ineffectiveness of these bans.
