The slope of the least squares regression line is 1.0 and the y-intercept is 6.3
<h3>How to determine the slope?</h3>
To do this, we enter the data values in a graphing calculator, and we interpret the results:
Using a graphing calculator, we have the following calculation summary
- Sum of X = 83
- Sum of Y = 123
- Mean X = 13.8333
- Mean Y = 20.5
- Sum of squares (SSX) = 356.8333
- Sum of products (SP) = 365.5
- R = 0.8728
The slope (b) is calculated using:
b = SP/SSX
This gives
b = 365.5/356.83
b = 1.0
Hence, the slope is 1.0
<h3>How to determine the y-intercept?</h3>
The y-intercept (a) is calculated using:
a = MY - bMX
a = 20.5 - (1.02*13.83)
a = 6.3
Hence, the y-intercept is 6.3
<h3>How to determine the correlation coefficient?</h3>
In (a), we have:
R = 0.8728
Approximate
R = 0.9
This means that the correlation coefficient is 0.9

34/32 can also be written as 1.0625 or 1 & 1/16.
$22,000 * 0.12 = $2,640
so
$22,000 - $2,640 = $19,360
so
$19,360 after 1 year.
$19,360 * 0.12 = $2,323.20
$19,360 - $2,323.20 = $17,036.80 (2 years)
$17,036.80 * 0.12 = $2,044.416
Don't round until you finish the problem.
$17,036.80 - $2.044.416 = $14,992.384 (3 years)
$14,992.384 * 0.12 = $1,799.08608
$14,992.384 - $1,799.08608 = $13,193.29792 (4 years)
ROUND
$13,193.29792 rounded to $13,193.30
