y = 0 for the x-intercept, so
2х - 5*0 = 60
2x = 60
x = 60/2 = 30
(30, 0)

x = 0 for the y-intercept, so:
2*0 - 5x = 60
-5x = 60
5x = -60
x = -30/5 = -12
(0, -12)

Answer is a) (0, -12)(30, 0)

A researcher collected data on the hours of TV watched per day from a sample of five people of different ages. Here are the resu

Answer:

1. The least squares regression is y = -0.1015·x + 6.51

2. The independent variable is b) age

Please see attached table

Step-by-step explanation:

The least squares regression formula is given as follows;

$\dfrac{\sum_{i = 1}^{n}(x_{i} - \bar{x})\times \left (y_{i} - \bar{y} \right ) }{\sum_{i = 1}^{n}(x_{i} - \bar{x})^{2}}$

We have;

$\bar x$ = 24

$\bar y$ = 4

$\Sigma (x_i - \bar x) (y_i - \bar y)$ = -79

$\Sigma (x_i - \bar x)^2$ = 778

$\therefore \hat \beta =\dfrac{\sum_{i = 1}^{n}(x_{i} - \bar{x})\times \left (y_{i} - \bar{y} \right ) }{\sum_{i = 1}^{n}(x_{i} - \bar{x})^{2}} = \frac{-79}{778} = -0.1015$
