Respuesta :
The right choice is (C) 91. The correlation between the variables x and y is significant.
Using a regression line, it is possible to predict a student's score if they study seven hours.
A regression line usually looks like this:
y = α + βx
In this case, Y is the dependent variable, and X is the independent variable.
The equation for regression is:
y = 56.114 + 5.044 x
Determine the value of y as follows for x = 7:
y = 56.114 + 5.044 x
= 56.114 + (5.044 * 7)
= 91.422
≈ 91
Consequently, a student who studied for seven hours received a score of 91.
