The regression model that best fit the data set is : Y=10.35-0.0467X
Explanation:
The equation of a regression line is given by;
Y=a+bX where b is the slope of the line a is the y-intercept , Y is the dependent variable and X is the independent variable
The slope b is given by;
b = n(∑xy)-(∑x)(∑y) / n(∑x² )-(∑x)²
a=(∑y)(∑x²)-(∑x)(∑xy) /n(∑x²)-(∑x)²
n is the sample size = 4
Form a table as;
x y xy x² y²
2 13 26 4 169
4 8 32 16 64
5 7.5 37.5 25 56.25
8 12 96 64 144
<u>19 40.5 191.5 109 433.25--------sum</u>
<u></u>
a=(∑y)(∑x²)-(∑x)(∑xy) /n(∑x²)-(∑x)²
a=(40.5)(109) - (19)(191.5) / 4(109) - (19)²
a=(4414.5 - 3638.5) / (436-361)
a=776/75
a=10.35
b = n(∑xy)-(∑x)(∑y) / n(∑x² )-(∑x)²
b=4(191.5)-(19)(40.5) / 4 (109)-19²
b=766-769.5 /436-361
b=-3.5/75
b= - 0.04667
The model will be represented by the equation;
Y=10.35 -0.0466X

Answer:
Last year the polls kept showing that Hilary was beating Trump and she was going to win for sure. The same thing is happening this year. The polls they show on TV aren't always accurate. Plus all the Trump supporters will be voting him again. Also any Hilary voters that realized Trump wasn't half bad might be switching to him. Recently celeberties have been coming out as Trump supporters and as we all know celebs tend to have an impact on peoples decisions. So with that in mind that adds on more people who could be voting for Trump. CNN along with other news media have heavily against Trump so the polls they are showing on TV can be very biased. At this moment it is very possible for Trump to win. We just have to wait for the final say.
