A new industrial oven has just been installed at Piatt Bakery. To develop experience regarding the oven temperature, an Inspector reads the temperature at four different places Inside the oven each half hour starting at 8:00 a.m. The last reading was at 10:30 a.m., for a total of six samples. The first reading, taken at 8:00 a.m., was 347 degrees Fahrenheit. (Only the last two digits are given in the following table to make the computations easier.) Reading Time 1 3 4 8:00 a.m. 47 44 40 48 8:30 a.m. 49 48 45 48 9:00 a.m. 46 44 47 45 9:30 a.m. 10:00 a.m. 42 43 40 49 46 48 43 45 10:30 a.m. 35 67 45 45 E Click here for the Excel Data File a. On the basis of this initial experience, determine the control limits for the range, (Leave no cells blank - be certain to enter "O" wherever requlred. Round your Intermedlate calculations and final answers to 2 decimal places.) LCL UCL b. For each time period, is the temperature out of control? 8:00 a.m. 8:30 a.m. 9:00 a.m. 9:30 a.m. 10:00 a.m. 10:30 a.m.
