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

The two ways Mao Zedong Impose communism in China through the Cultural Revolution are deploying the Red Guards to intimidate Chinese intellectuals and commanding Red Guards to adhere to his beliefs.
Mao Zedong, often known as Chairman Mao, was a Chinese communist revolutionary who founded the People's Republic of China. From the PRC's founding in 1949 until his death in 1976, he served as the party's leader.

Mao Zedong wrote a letter to the Red Guards at Tsinghua University on August 1, 1966, expressing his personal endorsement and support for the group. Mao gave the cause a public boost during the "Red August" of Beijing by holding a sizable demonstration in Tiananmen Square on August 18.
