You are given the following information about x and y. x y Independent Dependent Variable Variable 15 5 12 7 10 9 7 11
The least squares estimate of b 0 equals .
a. 16.41176
b. â1.3
c. 21.4
d. â7.647

Step-by-step explanation:

Given

Required

The least square estimate

Calculate the mean of x

Calculate the mean of y

Calculate

Calculate

So:

Take LCM

rounding to the nearest thousandth would be 452,000

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
