PLZ ANSWER ASAP!!!!! Part B

Answer 1

The equation of the linear regression  is $\^ y = 3.58125\^x + 202.575$

Graphing tool

To determine the line of best fit, we make use of a graphing tool

See attachment for the graph of the line of best fit

The equation

From the graphing tool, we have the following calculation summary

• Sum of X = 440
• Sum of Y = 3601.5
• Mean X = 44
• Mean Y = 360.15
• Sum of squares (SSX) = 1440
• Sum of products (SP) = 5157

The regression Equation is then represented as:

$\^y = b\^x + a$

Where:

$b = \frac{SP}{SSX}$ and $a = \bar y - b \times \bar x$

$b = \frac{5157}{1440}$

$b = 3.58125$

Also, we have:

$a = \bar y - b \times \bar x$

$a= 360.15 - (3.58\times 44)$

$a = 202.575$

So, the linear regression equation is:

$\^ y = 3.58125\^x + 202.575$
