A value has been measured by Instrument A 33 times with a standard deviation of 4.3. Another value has been measured 7 times with Instrument B. Within what range will the standard deviation of the Instrument B observation have to fall to be considered equivalent quality at a 95% confidence level? Hint: Use the F-Distribution.
ham A beam of circular cross- section is subjected to pure bending moment M and the bending stresses are given by the following equation: 32 Мь ла where d is the diameter of the beam. It has been observed that the diameter (d) of the beam is a normally distributed random variable with a mean of 50 mm and a standard deviation of 0.125 mm. The bending moment (M) is also a normally distributed random variable with a mean of 1750 N-m and a standard deviation of 150 N-m. Determine the mean and standard deviation of the corresponding bending stress variable (o). Comment on the analysis.
A work sampling study of dockworkers must be set up. There will be a large number of random observations. However, for this exercise, determine an observation schedule (arranged chronologically) for six observations. Assume workers are on the docks for eight hours a day, and that the study will be done over a 60-day period. Use the random digits listed below.

Test the claim that the samples come from populations with the same mean. Assume that the populations are normally distributed with the same variance. 1) Given the sample data below, test the claim that the populations have the same mean. Use 1) a significance level of 0.05. Brand A n = 10 x = 32.1 s2 = 4.37 Brand B n = 10 x = 32.6 s2 = 3.61 Brand C n = 10 x = <= 27.2 s² = 3.34

A light bulb manufacturer wants to maximize bulb lifetime. Four parameters are to be tested: Parameters a and b are the concentrations of a certain alloys in the filament. Parameters c and d are the temperature and speed, respectively, at which the filaments are extruded in the manufacturing process. A three-level experiment is be used. Levels 1, 2, and 3 correspond to low, medium, and high values of each respective parameter. Taguchi's 9-run design array (as in the learning module) is to be used. For each experimental run, thirty bulbs are tested, and the mean time to failure (MTTF) for each run is recorded as X₁, X₂, etc. These values, in order, are 1318, 1375, 1414, 1490, 1532, 1296, 1455, 1219, and 1266 hours, to four significant digits. (a) Generate a table with the above values configured as a Taguchi 9-run design array (Excel is recommended). Calculate all 12 level averages, i.e. Xal, Xa2, X3, Xb₁‚ Ãµ2, Xd3 (b) Generate four plots, showing the dependence of X on each parameter.…

A company makes electrical resistors. The perfect resistor has a value of 400 ohms. A sample of 2000 resistors was tested and found to have a mean of 391.5 ohms and a standard deviation of 22.5 ohms. Assuming a normal distribution:a. How many resistors in the sample will have more than 440 ohms of resistance?b. How many resistors in the sample will have less than 360 ohms of resistance? note: you can use the frequency distribution table picture I attached.
