Answer the following questions about the sphere whose equation is given by $x^2 + y^2 + z^2 - 8x + 6y = 24$. 1. Find the radius of the sphere. Radius: $r = ?$ 2. Find the center of the sphere. Write the center as a point $(a, b, c)$ where $a$, $b$, and $c$ are numbers. Center: $?$ Recall that the standard equation of a sphere with center $(a, b, c)$ and radius $r$ is $(x - a)^2 + (y - b)^2 + (z - c)^2 = r^2.$

Problem Statement: Sail Toad Cycling seeks to understand how various factors influence bicycle performance in road races. They have enlisted a number of amateur bike racers to take part in a designed experiment. Sail Toad Cycling seeks to create an empirical model of performance based on three factors: tire pressure, drag, and chain lubrication. Racers compete individually on a 30-mile course with some significant hills. Experiment: Sail Toad Cycling has designed a 2-level 3-factor Full Factorial matrix experiment with the time trial results as the output variable. The results shown in the table below are the average result of many racers at each combination of independent variables. The matrix is populated with full randomization of the population of racers with an equal number of racers at each of the 8 corners of the test matrix. The time trial results at each corner are the average of the number of racers. Sail Toad Cycling has asked you to analyze these results. Data: Matrix P = Tire Pressure (psi) 1 80 2 100 80 4 100 5 80 6 100 7 80 8 100 D = Drag Coefficient L = Chain lubrication (grams) 0.80 1 0.80 1 0.90 1 0.90 1 0.80 5 0.80 5 0.90 5 0.90 5 R = Time (minutes) 61 57 70 66 57 53 68 64 Assignment: 1. Create and display a response cube with the response variable R being time. 2. Compute the average response (time) at the design center of the experimental space. 3. Calculate the main effects and two-way interactions. 4. Create an empirical model of the response space. 5. Verify your empirical model by checking several corners. 6. What are the interactions between the independent variables? 7. Based on the data provided, find the combination of variables for optimal performance. 8. Make a meaningful recommendation(s) as to how to improve racer performance.
