- Murder was committed in an air-conditioned laboratory. Dr. Quincy, the medical examiner, was summoned to the scene of the crime. One of the first things he did was to take the temperature of the corpse. At 9:23 PM, he recorded the temperature to be 20.1oC and at 9:53 Pm to be 18.7oC. He further observed that the thermostat of the air-conditioning unit was set at 16oC. After gathering all pertinent data and analyzing them for sometime, he submitted a preliminary report stating that the victim was murdered between 7 PM and 8 PM. Was Dr. Quincy's report correct? At what approximate time did the victim die? Assume that the normal body temperature of a human being, alive and well, is 37oC.Thank you very much for answering me. Can you please answer the d sub parts. The corrosion loss (in mm) was measured for eight specimens of a certain steel alloythat had been immersed in brine. The measurements were0.3457,0.3755 , 0.3563, 0.3663, 0.3861,0.4007, 0.3429, 3769 .a. Make a dotplot of the eight values.b. Should the Student’s ? distribution be used to find a 99% confidence interval for the meancorrosion loss? If so, find the confidence interval. If not, explain why not.c. Eight independent measurements are taken of the corrosion loss for a different alloy. Themeasurements this time are: 0.3633, 0.4215 , 0.3429, 0.3501, 0.4974, 0.3678, 0.3896,and 0.3791. Make a dotplot of these values.d. Should the Student’s ? distribution be used to find a 95% confidence interval for the meancorrosion loss for this alloy? If so, find the confidence interval. If not, explain why notFor Numbers 21 to 25: Capsaicin content in red habanero chilli (Capsicum chinense Jacq.) is affected drying temperatures (60 °C, 70 °C, and 80 °C) using an oven. Samples of red habanero chilli were procured. Upon checking, there were varying sizes of chilli and thus the experimenter grouped the oy the arying process. An experiment was conducted to determine the effect of using different Mocured, Opon checking, there were varving sizes of chilli and thus the experimenter grouped the Samples according to size. Drying temperatures were then randomly assigned within each group for o nours. The capsaicin content was measured for each sample.

- A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples;then compare the variation. a. The coefficient of variation for the systolic measurements is (Type an integer or decimal rounded to one decimal place as needed.) b. The coefficient of variation for the diastolic measurements is (Type an integer or decimal rounded to one decimal place as needed.)Suppose the 24 soil samples have widely different pH values.

What is the percentage of matter in the ore that is neither gold or silver?
- The angronomist realized that he wanted his results to apply over a range of soil conditions. So, he decided to conduct his experiment on 4 different locations (subdivisions) in a field so that the elevation and type of soil vary. He planted each variety on one plot within each subdivision of the field. Again, the yields in lbs/acre wre recorded for each plot. a) What is the response? b) What is the factor and factor levels? c) What are the treatments? What are the blocks? d) What are the experimental units?Find the chara oderietin palynourel of the amatrex 3. 2.An insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year. The results are shown below. Under Age 18 Over Age 18 n1 = 500 n2 = 600 Number of accidents = 180 Number of accidents = 150 We are interested in determining if the accident proportions differ between the two age groups.
- A metal casting process for the production of turbine blades was studied. Three factors were varied. They were A: the temperature of the metal, B: the temperature of the mold, and C: the pour speed. The outcome was the thickness of the blades, in mm. The results are presented in the following table. Thickness 4.61 B -1 -1 -1 -1 -1 4.51 -1 -1 4.60 -1 4.54 -1 4.61 4.61 -1 4.48 4.51 a. Compute estimates of the main effects and the interactions. b. Is it possible to compute an error sum of squares? Explain. Plot the estimates on a normal probability plot. Does the plot show that some of the factors influence the thickness? Éxplain. C.One operation of a mill is to cut pieces of steel into parts that will later be used as the frame for front seats in an automobile. The steel is cut with a diamond saw and requires the resulting parts to be within 10.005 inch of the length specified by the automobile company. Data are collected from a sample of 50 steel parts and are shown in the following table. The measurement reported is the difference in inches between the actual length of the steel part, as measured by a laser measurement device, and the specified length of the steel part. For example, the first value, -0.003, represents a steel part that is 0.003 inch shorter than the specified length. Complete parts a through c Click the icon to view the data table. a.
