12.The accuracy of an oven thermostat is being tested. The oven is set to 360F, and the temperature when the thermostat turns off is recorded. A sample of size 7 yields the following results: 358 363 361 355 367 352 368 a) Put the values in L1 and go through the steps outlined at the end of Chapter 7 to assess normality 1. [2] Create a Normal Plot and circle the diagram that matches your calculator screen 2. [3] Trace through the coordinates and capture the Normal Scores (to 2 decimafplaces) associated with each data value: r = (to three decimaf places) 4. [2] Compare rto the Critical Value ( ) in the table on the bottom of page 12 in your Chapter 7 packet. Do you have a significant correlation? YES NO 5. [2] Now create a modified boxplot to determine whether there are outliers. Sketch your plot: b) [1] Is it reasonable to treat this as a sample from an approximately normal population
