Question: An article in Industrial Quality Control 1956 pp 5 8 describes
An article in Industrial Quality Control (1956, pp. 5–8) describes an experiment to investigate the effect of glass type and phosphor type on the brightness of a television tube. The response measured is the current necessary (in microamps) to obtain a specified brightness level. The data are shown in Table 8E.1. Analyze the data and draw conclusions.
Answer to relevant Questionsa. Prepare a normal probability plot of the effects. Which effects seem active? Fit a model using these effects. b. Calculate the residuals for the model you fit in part (a). Construct a normal probability plot of the ...An experiment was run to study the effect of two factors, time and temperature, on the inorganic impurity levels in paper pulp. The results of this experiment are shown in Table 8E.5: a. What type of experimental design has ...Four factors are thought to possibly influence the taste of a soft-drink beverage: type of sweetener (A), ratio of syrup to water (B), carbonation level (C), and temperature (D). Each factor can be run at two levels, ...A component has a Weibull time-to-failure distribution. The value of the scale parameter is . Suppose that the shape parameter is . Find the mean and variance of the time to failure. What is the reliability at 600 ...Reconsider the component described in Exercise 9.1. What is the reliability of the component at 25,000 hours?
