Question

read the following description of a data set. camille manages the student health services department at manchester university. she suspects that the students poor breakfast habits are contributing to the schools academic decline. camille surveyed several students asking how many times they ate breakfast in the past month. she also checked each students gpa. the data shows the number of times each student ate breakfast in the past month, x, and his or her gpa, y. the least squares regression line of this data set is: y = 0.043x + 2.469 what gpa does this line predict for a student who ate breakfast 15 times this past month? round your answer to the nearest thousandth.

Explanation:

Explicación:

Paso1: Sustituir el valor de x

Sustituimos x = 15 en la ecuación $y = 0.043x+2.469$.
$y=0.043\times15 + 2.469$

Paso2: Realizar la multiplicación

Calculamos $0.043\times15 = 0.645$.
$y=0.645 + 2.469$

Paso3: Realizar la suma

Sumamos $0.645+2.469 = 3.114$.

Respuesta:

3.114
