IIlustration 23.7. It was found that when a manufacturing process is under control, the average number of defectives per sam- ple batch of 10 is 1.2. What limits would you set in a quality con- trol chart based on the proportion of defectives in sample batches of 10?
A fabric manufacturer employs a control chart to monitor stained fabric rolls in their production runs. The results of their process were inspected for 20 days taking the day's production as a sample, giving the results shown in the table below: (Image attached) Use this data to construct a control chart for stained rolls of fabric. Is the process under control? What limits would you recommend to control future production? Do not use an average size of the number of rolls.

A photoconductor film is manufactured at a nominal thickness of 25 mils. The product engineer wishes to increase the mean speed of the film, and believes that this can be achieved by reducing the thickness of the film to 20 mils. Eight samples of each film thickness are manufactured in a pilot production process, and the film speed (in microjoules per square inch) is measured. For the 25-mil film, the sample data result is = 1.13 and 81 = 0.11, while for the 20-mil film, the data yield = 1.08 and 82 = 0.09. Note that an increase in film speed wwould lovwer the value of the observation in microjoules per square inch. (a) Do the data support the claim that reducing the film thickness increases the mean speed of the film? Use a = 0.10 and assume that the two population variances are equal and the underlying population of film speed is normally distributed. What is the P-value for this test? Round your answer to three decimal places (e.g. 98.765). The data v the claim that reducing the…

An engineer in charge of a production process that produces a stain for outdoor decks has designed a study to test the research hypothesis that an additive to the stain will produce an increase in the ability of the stain to resist water absorption. The mean absorption rate of the stain without the additive is 40 units. The enginner places that stain with the additive on n=50 pieces of decking material and records y=36.5 and s=13.1. Let μ denote the mean absorption rate of the stain. You must state the null hypothesis and the alternative hypothesis. Use a=0.05

Eight samples of each film thickness are manufactured in a pilot production process, and the film speed (in microjoules per square inch) is measured. For the 25-mil film, the sample data result is.x₁ = 1.15 and S₁ = 0.11, while for the 20-mil film, the data yield 2 = 1.06 and s2 = 0.09. Note that an increase in film speed would lower the value of the observation in microjoules per square inch. Do the data support the claim that reducing the film thickness increases the mean speed of the film? Use a = 0.10 and assume that the two population variances are equal and the underlying population of film speed is normally distributed. The appropriate decision for the test is to reject the null hypothesis True False

W The diameter of the earth's moon is 2,159 miles. The diameter of Jupiter is 86,881 miles. a) How many of earth's moons could fit across the diameter of Jupiter? Round your answer to the nearest whole number. b) The average distance between earth and its moon is 384,400 kilometers. At their closest point (when both planets are lined up on the same side of the sun), the distance between earth and Jupiter is 588,000,000 kilometers. Using these two distances, and the fact that 1 kilometer = 0.62 miles, how much further away from earth (in miles) is Jupiter than our moon? 80°F hp ho 12 AA & 4. 08.

The Environmental Protection Agency (EPA) requires that cities monitor over 80 contaminants in their drinking water. Samples from the Lake Huron Water Treatment Plant gave the results shown here. All observations were below the allowable maximum, as shown by the reported range of contaminant levels. (presumably the mean would be the midrange). Substance Range Detected AllowableMaximum Origin of Substance Chromium 0.47 to 0.69 100 Discharge from steel and pulp mills, natural erosion Barium 0.004 to 0.019 2 Discharge from drilling wastes, metal refineries, natural erosion Fluoride 1.07 to 1.17 4 Natural erosion, water additive, discharge from fertilizer and aluminum factories For each substance, estimate the standard deviation σ by assuming uniform distribution and normal distribution shown in Table 8.11 in Section 8.8.

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 45 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that o = 7.10 ml/kg for the distribution of blood plasma. When finding an 99% confidence interval, what is the critical value for confidence level?
