Chapter 2: Q27. (page 86)

For exercise 25-30, use the following information.
A median-fit line is a particular type of line of fit. Follow the steps below to find the equation of the median-fit line for the data.
27. Find Y, the y-coordinate of the point on the line in Exercise 26 with an x-coordinate of $x_{2}$ .

Short Answer

Expert verified

The value of $Y = 354$ .

Step by step solution

Step-1 – Equation of line.

We know that the medians of x-values $x_{1} = 1988, x_{2} = 1993, x_{3} = 1998$ and medians of y-values is $y_{1} = 247, y_{2} = 360.5, y_{3} = 461$

The equation of line is $y = 21.4 x - 42, 296.2$ .

Step-2 – Substitute the respective values.

Substitute $x_{2} = 1993, y = Y$ into $y = 21.4 x - 42, 296.2$

$Y = 21.4 (1993) - 42, 296.2$

Step-3 – Simplify the equation.

$\begin{array}{l} Y = 21.4 (1993) - 42, 296.2 \\ Y = 42, 650.2 - 42, 296.2 \\ Y = 354 \end{array}$

The value of $Y = 354$ .
