Determine the number of bags sold
First, we need to determine the number of bags for 27 pears;
Since they are packed in 3s
Hence:
9 bags were used for 27 pears;
After 5 bags were sold, we have:
Recall that the pears are packed in 3s
So:
Given the model of the Exponential Regression:
By definition:
You can see in the table the observed y-values (the temperature in Fahrenheit)
In order to find the Predicted y-values, you need to substitute all the x-values given in the table (the time in minutes) into the equation and then evaluate. You get:
Now you have these points:
Therefore, you can plot them on the Coordinate Plane:
By definition, when the residual plot shows a pattern, a non-linear regression model is appropriate for the data. Therefore, the Exponential Regression Model is a good fit.
Hence, the answer is:
- Residual Plot:
- First option.
