A study was conducted to compare the breaking strength of fabric treated by two commercial durable press process. 1 and process 2. Five specimens of the same material were assigned to process 1 and another independent sample of five specimens to process 2. Process 1 the mean was 29.54 with a standard deviation of 1.17. Process 2 the mean was 25.20 with a standard deviation of 2.67. Find a 95% confidence interval for the difference in mean pounds to cause a tear for between process 1 and process 2.

Notice sample size is less than 30.
