Exercise 5.6 Temperature MeasurementThe temperature of a fluid in a chemical manufacturing process is measured 25 times.It can be assumed, that there is in fact no change in the temperature of the fluid at all.Nevertheless the measurement instrument determines the following values:Measurementnumber:1234578Measuredvalue:49.98 49.49 50.06| 49.96 49.96 49.9449.7750.04 49.88Measurementnumber:101112131415161718Measuredvalue:49.83 50.11 50.02 49.78 50.0149.7550.13 50.23 50.00Measurementnumber:19202122232425Measuredvalue:50.13 49.49 50.00 | 49.80 49.98 49.84 49.77Table 1: Measured temperatures.a) Sketch a histogram of the measured values!b) Calculate the sample mean and the sample variance!c) Assume that the variance is constant for any temperature level. A new measurementis carried out and the measurement instrument displays a temperature of 75°C. Inwhich range will the true temperature be, if we accept a maximum error probabilityof 0.3%?d) What can be done to improve the accuracy of the temperature measurement withoutchanging the measurement instrument?

A histogram is the pictorial representation of the data values with frequency for a range. The…

When purifying drinking water you can use a so-called membrane filtration. In an experiment one wishes to examine the relationship between the pressure drop across a membrane and the flux (flow per area) through the membrane. We observe the following 10 related values of pressure (x) and flux (y): 1 2 3 4 5 7 8. 9 10 Pressure (x) 1.02 2.08 2.89 4.01 5.32 5.83 7.26 7.96 | 9.11 9.99 Flux (y) 1.15 0.85 1.56 1.72 4.32 5.07 5.00 5.31 6.17 7.04 (a) Fit the least square regression equation to predict the flux (flow per area) through the pressure drop across a membrane. (b) Find the estimated flux when the pressure drop across a membrane is 4.50. (c) Calculate the coefficient of correlation. Interpret your result. (d) Given Sxx = 83.25961 and Se = 0.64460653. Test, at the 0.01 level of significance, whether there is linear relationship between the pressure drop across a membrane and the flux (flow per area) through the membrane. (e) Construct a 98% confidence interval for the mean flux for the…

Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data
