Question

read the following description of a data set. a reporter for a college magazine is writing a feature about student participation in on - campus organizations. she wants to see if there is a relationship between student population and the number of on - campus organizations. to begin, she recorded the number of students, x, and the number of officially recognized student organizations, y, for several colleges. the least squares regression line of this data set is: y = 0.311x - 1,856.997. how many student organizations does this line predict for a college with 9,221 students? round your answer to the nearest integer.

Explanation:

Explicación:

Paso 1: Sustituir el valor de x

Dado que $x = 9221$, sustituimos en la ecuación $y = 0.311x-1856.997$.
$y=0.311\times9221 - 1856.997$

Paso 2: Realizar la multiplicación

$0.311\times9221=2867.731$. Entonces $y = 2867.731-1856.997$.

Paso 3: Realizar la resta

$y=2867.731 - 1856.997=1010.734$.

Paso 4: Redondear al entero más cercano

Redondeando $1010.734$ al entero más cercano, obtenemos $1011$.

Respuesta:

$1011$
