Statistics Question. Use the Desmos graphing calculator to find the least-squares regression line for the dataset in the table:

Soloha48 [4]

Given:

The table of values.

To find:

The least-squares regression line for the data set in the table by using the desmos graphing calculator.

Solution:

The general form of least-squares regression line is:

$\hat{y}=mx+b$ ...(i)

Where, m is the slope and b is the y-intercept.

By using the desmos graphing calculator, we get

$m\approx 2.55,b\approx -6.435$

Substitute these values in (i).

$\hat{y}=(2.55)x+(-6.435)$

$\hat{y}=2.55x-6.435$

Therefore, the correct option is A.

nydimaria [60]

$\sf f(x) = 3 \ * \ 2^x$

insert x = -2

$\sf f(-2) = 3 \ * \ 2^{-2}$

$\sf f(-2) = 3 \ * \ \dfrac{1}{4}$

$\sf f(-2) = \dfrac{3}{4}$

option D. 3/4 will be the correct answer.
