For the regression equation and e the number of kilowatt-hours, in thousands, for a six-room house is mathematically given as

Y = 1.33-0.667X and 5.3332

<h3>What is the number of kilowatt-hours, in thousands, for a six-room house?</h3>

Generally, the equation for the standard deviation is mathematically given as

$s$ ₓ = $\sqrt{\frac{\sum\(X-\=X)^2}{n-1} }$

= $\sqrt{\frac{66.9}{10-1} }$

= 2.72

$s_y$ = $\sqrt{\frac{36.4}{10-1} }$

= 2.01

therefore correlation coff

r = $\frac{44.6}{(10-1)(2.72)(2.01)}$

r = 0.9038

In conclusion the regression equation is given

b = r_sy/sx

b = (0.9038)(2.01/2.72)

= 0.667

intercept

a = 7.4-0.667(9.1)

a = 1.33

The regression equation is

Y = 1.33-0.667X

(b) number of kilowatts x = 6 house

Y = 1.33-0.667X

Y = 1.33-0.667(6)

= 5.3332
