In 2012, entering freshmen at the UA have an average ACT score of 25.4 with a standard deviation of 2.1. 1. What is the probabil

astra-53 [7]

Answer:

P [ Z > 24,1 ] = 72,24 %

Step-by-step explanation:

P [ Z > 24,1 ] = 1 - P [ Z < 24,1 ]

P [ Z < 24,1 ] = ( Z - μ₀ ) / σ

P [ Z < 24,1 ] = ( 24,1 - 25,4) / 2,1

P [ Z < 24,1 ] = - 1,3/ 2,1

P [ Z < 24,1 ] = - 0,6190 ≈ - 0,62

We look in z-table and find for z(score) -0,6190

P [ Z < 24,1 ] = 0,27763

Then

P [ Z > 24,1 ] = 1 - 0,27763

P [ Z > 24,1 ] = 0,72237 ⇒ or P [ Z > 24,1 ] = 72,24 %

2) Un parque cuadrado tiene una superficie de 1600 m2. Si corres alrededor del parque dando 6 vueltas a su alrededor. ¿Cuántos m

elena-s [515]

Respuesta:

960 m

Explicación paso a paso:

Paso 1: Información provista

Superficie del parque (S): 1600 m²

Paso 2: Calcular cuanto mide cada lado (l) del parque

El parque es un cuadrado, por lo que podemos encontrar la longitud del lado usando la siguiente fórmula.

S = l²

l = √S = √1600 m² = 40 m

Paso 3: Calcular el perímetro del parque (P)

El perímetro es la cantidad de metros que reccorre cuando da una vuelta completa.

P = 4 l = 4 × 40 m = 160 m

Paso 4: Calcular la distancia recorrida cuando corre 6 vueltas

Debemos multiplicar el perímetro por 6.

6 × 160 m = 960 m

A researcher decides to split scores on an exam into quartiles. She determines that a score of 64 is at the 25th percentile, a s

wariber [46]

Answer: IQR = 16

Step-by-step explanation:

The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.

percentage : 25 50 75

score : 64 74 80

Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.

If the number of observations is odd, then the median is observation

term

If the number of observations is even, then the median is observation and observations.

given n=3, middle term is '74'

In this given data the median is (M) = 74

Interquartile range IQR = median of upper half-median of lower half

= 80-64

= 16

IQR = 16
