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.
200 people were randomly sampled and asked what they regularly eat for breakfast or lunch. Each person was identified as either a consumer or a non consumer of high-fiber cereals, and the number of calories consumed at lunch was measured and recorded. These data are summarized below; Consumer of high fiber cereals Non consumer of high fiber cereals η1 =41 η2 = 159 Mean 1 =603 Mean 2 =639 Stanadard deviation 1 = 110 Standard deviation 2 = 141 If the scientist claims that people who eat high fiber cereals for breakfast do consume on average fewer calories for lunch than people who don’t eat high fiber cereals for breakfast, and if it is true, high fiber cereal manufacturer will be able to claim another advantage of eating their products-potential weight reduction for dieter. REQUIRED Are there sufficient evidence at 5% significance level to support the above claim?

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.

9.) A researcher is testing the reliability of a new method of growing culinary herbs. It is know that the average time to germination (for the plant to sprout from the seed) for basil grown with the traditional method is μ=7.0μ=7.0 days with a standard deviation of σ=1.8σ=1.8 days. The researcher tests the new method on 36 plants to see if there is any difference between the two methods in the time to germination for basil plants and finds that the average time germination with the new method is x¯¯¯=8.0x days. What is the alternate hypothesis that the researcher is testing?
