Answer:

PREGUNTA 17 - 1 PUNTO

Se sabe que leer un nombre en voz alta puede mejorar la memoria. A un psicólogo le gustaría probar la afirmación de que los adultos pueden

recordar más del 55 por ciento de los nombres de una lista, en promedio, después de leer la lista en voz alta. Para probar esta afirmación en el

nivel de significación, el psicólogo recopila los siguientes datos en una muestra de 50 participantes y registra el porcentaje de

nombres recordados en la lista después de leerla en voz alta. Los siguientes son los datos de este estudio:

Tamaño de la muestra = 50 participantes

Media de la muestra = 60 por ciento

A partir de datos anteriores, se sabe que la desviación estándar de la población es del 15 por ciento.

Trabaje con el procedimiento de prueba e interprete los resultados de la prueba de hipótesis. ¿Cuál es tu conclusión?

No se puede rechazar la hipótesis nula. NO hay pruebas sólidas para concluir que los adultos pueden recordar más

del 55 % de los nombres de una lista, en promedio, después de leer la lista en voz alta.

No se puede rechazar la hipótesis nula. Existe una fuerte evidencia para concluir que los adultos pueden recordar más que

los nombres en una lista, en promedio, después de leer la lista en voz alta.

Rechazar la hipótesis nula. NO hay evidencia sólida para concluir que los adultos pueden recordar más de 5

nombres en una lista, en promedio, después de leer la lista en voz alta.

Rechazar la hipótesis nula. Existe una fuerte evidencia para concluir que los adultos pueden recordar más del 55%

de los nombres en una lista, en promedio, después de leer la lista en voz alta.

(5372 + 100y^2) + 5(10y^2 – 110) Add the two polynomials and write in the form ay^2 + b, where a and b are constants, What is th
dangina [55]

Answer:

The value of a is 150 and b is 4822.

Explanation:

First, you have to expand to remove brackets :

(5372 + 100 {y}^{2} ) + 5(10 {y}^{2}  - 110)

= 5372 + 100 {y}^{2}  + 50 {y}^{2}  - 550

Next, you have to simplify :

100 {y}^{2}  + 50 {y}^{2}  + 5372 - 550

= 150 {y}^{2}  + 4822

Next, you have to compare it :

a {y}^{2}  + b = 150 {y}^{2}  + 4822

a = 150

b = 4822
