Answer:
a. ![y= 130x + 350 + \epsilon](https://tex.z-dn.net/?f=y%3D%20130x%20%2B%20350%20%2B%20%5Cepsilon)
b. The symbol y-bar represents the average price of hotels in the area
Step-by-step explanation:
a. The regression line equation is given by:
![y=\alpha x + \beta + \epsilon](https://tex.z-dn.net/?f=y%3D%5Calpha%20x%20%2B%20%5Cbeta%20%2B%20%5Cepsilon)
Where Alpha represents the slope, Beta represents the intercept with the Y axis, and epsilon represents the random component of the model. Thus,
y
Obtaining:
.
b. In a simple linear regression model the value of y-bar represents the average of all values of y observed. Thus, since y represents the prices of the hotels, then y-bar is the average price of hotels in the area.

5w=-5
w=-1
You already have figured the main idea. In this case, the population is growing 1.9% a year. This word can be translated into: multiplied by 101.9% (100+1.9%). That means the P0 is 6 bill, the base is 101.9%(or 1.019) and the time is 50 years. The calculation would be:
<span>P(t)=P₀a^t
</span>P(t)=6 billion * 101.9%^50= 6 billion * <span>2.56276= 15.38 billion</span><span>
