A graphing calculator finds the regression line to be
y = 5.5x + 52
y = 5.5x + 52
Answer:
B. [tex]y=5.5x+52[/tex]
Step-by-step explanation:
We are given the data set,
x y
2 65
4 74
6 81
8 96
10 109
Now, using the regression calculator, we get that,
The linear equation for that matches the data is [tex]y=5.5x+52[/tex].
So, option B is correct.
