Problem 1

Problem 1
Home products Inc. is considering marketing a long-lasting car wax. Three different waxes (Type 1, Type 2, and Type 3) have been developed. Are the three waxes equally effective? Be prepared to answer any questions concerning this problem.
In order to test the durability of these waxes, 5 new cars were waxed with Type 1, 5 with Type 2, and 5 with Type 3. Each car was then repeatedly run through an automatic carwash until the wax coating showed signs of deterioration. The number of times each car went through the carwash is shown below. The design is randomized single factor of type of wax.
Are the three waxes equally effective? Be prepared to answer any questions concerning this problem.

Each car was then repeatedly run through an automatic carwash until the wax coating showed signs of deterioration. The number of times each car went through the carwash is shown below. The design is randomized two factors of car type and type of wax. Discussion was to block on different cars, because the car type may have a different effect that cannot be controlled.
Are the three waxes equally effective? Be prepared to answer any questions concerning this problem.

Each car was then repeatedly run through an automatic carwash until the wax coating showed signs of deterioration. The number of times each car went through the carwash is shown below. The design is randomized two factors of car type and type of wax. Discussion was to make sure that we replicate the design and block on different cars, because the car type and time may have a different effect that cannot be controlled.
