"Durable Press" cotton fabrics are treated to improve their recovery from wrinkles after washing. The treatment also reduces the strength of the fabric compared breaking strength of untreated fabric with that of fabrics treated by three commercial durable press processes. Is there evidence to support claim that the mean breaking strength of the different fabrics is different? Use a significance level of 0.05.
