Extracted text: Calibrating a scale: Making sure that the scales used by businesses in the United States are accurate is the responsibility of the National Institute for Standards and Technology (NIST) in Washington, D.C. Suppose that NIST technicians are testing a scale by using a weight known to weigh exactly 1000 grams. The standard deviation for scale reading is known to be a- 3.1. They weigh this weight on the scale 55 times and read the result each time. The 55 scale 999 grams. The calibration point is set too low if the mean scale reading is less than 1000 grams. The technicians want to readings have a sample mean of x perform a hypothesis test to determine whether the calibration point is set too low. Use a =0.01 level of significance and the critical value method.
