Answer:
<h2>6 cups of hot chocolate cost $1.50.</h2>Step-by-step explanation:
According to the problem, the graph is modeled by the relation
So, we can observe that x-values refer to cups of hot chocolate, and y-values refer to price in dollars.
If we need to find the proce for 6 cups of hot chocolate, we just need to replace into the given relation, as follows
Therefore, 6 cups of hot chocolate cost $1.50.

The estimated regression equation:
ŷ = 2.73953X + 27.91395
Where ;
X = independent variable
ŷ = predicted or dependent variable
27.91395 = intercept
C.) To obtain the variation in sample values of height estimated by the model, we obtain the Coefficient of correlation:
Using the online pearson correlation Coefficient calculator :
The correlation Coefficient is 0.9696.
which means that the regression model estimated in part (b) explains approximately (0.9696 * 100) = 96.96% = 97% of the variation in the height in the sample.
