3. A variables sampling plan (VSP) for defectives is required for a process with two-sided spec limitsUSL/LSL = 75±5. The VSP must meet the following conditions■ Accept 95% of 0.5% defective lots (Hint: What are the AQL and alpha values?)■Reject 90% of 2% defective lots (Hint: What are the RQL and beta values?)a. Design the VSP assuming that the population standard deviation is known. (Assume σ =b. Design the VSP assuming that the population standard deviation is unknown.c. Should you accept or reject a lot in the σ unknown case if the sample delivers1)=72.0 andS = 1.5? (You don't have the sample data to use the MINITAB menu. You will have to do thecalculation by hand.)

For each of the studies presented below: (1) Define the population parameter of interest to the researchers and (2) Estimate the population parameter defined in (1), with a point estimate. (a) A 42-inch, large-screen, plasma TV is designed to consume only 350 watts and therefore produce less heat. In order to check this specification, a sample of plasma TVs was obtained and the power consumption was measured for each. The sample mean power consumption was 353.8 watts. (b) A sports physiologist is interested in the proportion of professional marathon runners who have very high haemoglobin counts. To this end, the researcher randomly selects 150 elite marathon runners, measures their haemoglobin levels and records it as either very high or normal. The researcher found that 48 subjects in the sample had very high haemoglobin counts.

17.34 (EX) Oligofructose and calcium absorption 1/6: Nondigestible oligosaccharides are known to stimulate calcium absorption in rats. A double-blind, randomized experiment investigated whether the consumption of oligofructose similarly stimulates calcium absorption in healthy male adolescents 14 to 16 years old. The subjects took a pill for nine days and had their calcium absorption tested on the last day. The experiment was repeated three weeks later. Some subjects received the oligofructose pill in the first round and then a pill containing sucrose (which served as a control). The order was switched for the remaining subjects. Here are the fractional calcium absorption data (in percent of intake) for 11 subjects: Subject Control 1 2 3 4 5 6 7 8 9 10 11 78.4 76.6 57.4 51.5 49.0 46.6 44.2 42.9 37.2 34.1 24.6 Oligofructose 62.0 95.1 46.5 49.4 89.7 43.8 50.3 51.6 66.6 52.7 54.0 Explain clearly why the matched pairs t test is the proper choice for this experimental design.
