Chapter 7.2, Problem 17P

In Problems 13–19, assume that the population of x values has an approximately normal distribution.

Diagnostic Tests: Total Calcium Over the past several months, an adult patient has been treated for tetany (severe muscle spasms). This condition is associated with an average total calcium level below 6 mg/dl (Reference: Manual of Laboratory and Diagnostic Tests by F. Fischbach). Recently, the patient’s total calcium tests gave the following readings (in mg/dl).

Chapter 7.2, Problem 17P, In Problems 1319, assume that the population of x values has an approximately normal distribution.

  1. (a) Use a calculator to verify that x ¯ = 9.95 and s ≈ 1.02.
  2. (b) Find a 99.9% confidence interval for the population mean of total calcium in this patient’s blood.
  3. (c) Interpretation Based on your results in part (b), does it seem that this patient still has a calcium deficiency? Explain.

Question 1 The data shown in Table 1 are and R values for 24 samples of size n = 5 taken from a process producing bearings. The measurements are made on the inside diameter of the bearing, with only the last three decimals recorded (i.e., 34.5 should be 0.50345). Table 1: Bearing Diameter Data Sample Number I R Sample Number I R 1 34.5 3 13 35.4 8 2 34.2 4 14 34.0 6 3 31.6 4 15 37.1 5 4 31.5 4 16 34.9 7 5 35.0 5 17 33.5 4 6 34.1 6 18 31.7 3 7 32.6 4 19 34.0 8 8 33.8 3 20 35.1 9 34.8 7 21 33.7 2 10 33.6 8 22 32.8 1 11 31.9 3 23 33.5 3 12 38.6 9 24 34.2 2 (a) Set up and R charts on this process. Does the process seem to be in statistical control? If necessary, revise the trial control limits. [15 pts] (b) If specifications on this diameter are 0.5030±0.0010, find the percentage of nonconforming bearings pro- duced by this process. Assume that diameter is normally distributed. [10 pts] 1
