Section 1 50 Points TABLE 1 Recently, a university switched to a new type of computer-based registration. The registrar is concerned with the amount of time students are spending on the computer registering under the new system. She decides to randomly select eight students on each of the 12 days of the registration and determine the time each spends on the computer registering. The range, mean, and standard deviation of the times required to register are in the table that follows. Day Range Mean Std.Dev 1 10 3.4949 2 31 15.250 10.3060 3 13 20.375 4.9262 4 21 22.875 8.3911 35 8.500 11.3767 6 18 7.875 9.5235 25 11.250 8.5815 9.5235 8 30 7.875 17 10.250 6.3640 9 10 7.8740 9.500 27 7.875 12.875 8.7086 9.3723 12 1) Referring to Table 1. an to constructed for the time required to register. The centerline of this R chart is located at ructed for the time required to register. 2) Referring to Table 1, an R is be multiplying m One way to create the lower control limit involves the of the sample ranges by D3. For this data set, the value of D3 is 3) Referring to Table 1, an R chart is to be constructed for the time required to register. One way to create the upper control limit involves ying the mean of the sample ranges by D4. For this data set, the value of D4 is Refening to Table 1, an R be constructed for the time required to register. The lower control limit for this data set is 5) Referring to Table 1. an R to be constructed for the time required to register. The upper control limit for this data set is
