Final answer:
To estimate the number of spotted trout at the south end of the lake after week 14 using quadratic regression, follow these steps: plot the data, perform quadratic regression, substitute the desired week into the equation, and solve for the estimated number of trout.
Step-by-step explanation:
To estimate the number of spotted trout at the south end of the lake after week 14 using quadratic regression, you will need a dataset that includes the number of trout and the corresponding week. Let's say you have a dataset of weekly trout counts. Here are the steps to perform quadratic regression:
- Plot the data points on a scatter plot, with the x-axis representing the weeks and the y-axis representing the number of trout.
- Using a calculator or a statistical software, perform quadratic regression on the data. This will give you a quadratic equation in the form of y = ax^2 + bx + c.
- To estimate the number of trout after week 14, substitute x = 14 into the quadratic equation and solve for y.
- The resulting value will be the estimated number of spotted trout at the south end of the lake after week 14.
