problem 2 and 3

Problem 2: Dr. Haramis wants to reduce the waiting times in her office. Six random observations of times spent between patient arrival and examination by the doctor were made over a period of 17 days Develop the appropriate control chart(s) and determine whether the process is in control (justify your conclusion) Day 1 1 29 24 ele 2 4 31 28 26 30 22 40 25 38 24 3 4 5 6 7 8 29 29 33 31 29 27 33 29 32 26 30 35 28 26 36 26 22 40 32 34 35 38 35 29 25 31 5 29 36 28 23 26 30 37 32 28 31 31 30 28 ***89*****83- & S&S G 31 30 33 28 32 29 34 30 29 26 27 32 30 26 10 29 34 27 30 35 25 11 12 13 30 14 15 16 17 88&a88 26 34 22 26 20 28 29 26 26 30 28 36 33 30 25 32 31 31 28 34 Problem 3: In the above scenario (problem 2), if patient surveys indicate that they are willing to wait between 10 and 30 minutes before seeing Dr. Harawis, is the process capable? Compute the cok to form your conclusion, and assume a process standard deviation of 2.5 minutes
