Answer:
y = 2.11926272 + 0.39484459x
correlation = 0.65293153
price = 4.09348567
Step-by-step explanation:
The equation of the regression line has that form:
y = a + bx, where a and b are the values given by the calculator.
So, replacing the values of a and b, we get:
y = 2.11926272 + 0.39484459x
On the other hand, the correlation is the value of r given by the calculator, so the correlation is 0.65293153
Finally, we can predict the price, replacing x with a certain percentage rate. Then, replacing x by 5%, we get:
y = 2.11926272 + 0.39484459x
y = 2.11926272 + 0.39484459(5)
y = 2.11926272 + 1.97422295
y = 4.09348567
So, the price predicted is 4.09348567.
Therefore, the answers are:
y = 2.11926272 + 0.39484459x
correlation = 0.65293153
price = 4.09348567
