A new medicinal drink is thought to help people stop smoking cigarettes. To test this, a random sample of 18 subjects agreed to drink one drink once a day for a month. Data is collected for these 18 subjects based on the number of cigarettes per day prior to starting the program, and the number of cigarettes per day after starting the program. Below is the data for these 18 subjects: Subject Number before Number after program 1 program 24 24 25 19 3 14 2 4 17 17 5 25 29 6 30 7 19 18 7 8 15 18 9 11 1 10 20 5 11 30 12 12 40 21 13 26 14 28 38 15 17 10 16 32 15 17 18 4 18 24 18 Using a sign test for matched pairs at the .01 level of significance, we will test the claim that the number of cigarettes smoked per day was less after the program
