- Find mZG. I 5/3 mZG = Submit % WThe amount of protein in a sample is measured by the samples absorbance of light at a given wavelength. Using standards, a best fit line of absorbance vs. mg protein gave the following parameters: m = 0.01630 sm = 0.00022 b = 0.1040 sb = 0.0026 An unknown sample has an absorbance of 0.246 ± 0.0059. What is the amount of protein in the sample?Artificial hip joints consist of ball and socket. As the joint wears, the ball (head) becomes rough Investigators performed wear tests on metal artificial hip joints. Joints with several different diameters were tested. The Following table presents measurements of head roughness (in nanometers). Diameter Head Roughness 16 0.83 2.25 0.40 2.78 3.23 28 2.72 2.48 3.80 36 6.49 5.32 4.59 a. Because the design is unbalanced, check that the assumption of equal variances is by showing that the largest sample standard deviation is less than twice as large as the smallest one. b. Construct an ANOVA table. c. Can you conclude that the mean roughness varies with diameter? Use the a=0.01 level of significance.
- Interpret effect size t(90)=4.06, p=.001, n2= .11 Small, medium, or largeRadon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L): 1.9 2.8 3.9 3.9 4.2 5.7 Find the variance and standard deviation (definitional formula). Show your work using a table.The rare earth element gadolinium is often used as a contrasting agent for MRIS. The concentration of gadolinium was measured in the discharge from a wastewater treatment plant near a large medical facility. Eight measurements were obtained: 1.254 ppm, 1.252 ppm, 1.246 ppm, 1.242 ppm, 1.815 ppm, 1.244 ppm, 1.251 ppm, 1.249 ppm. Use the Grubbs test to determine if one of these values is an outlier. What is the value of Geale? Should this potential outlier be rejected with 95% Gcalc = confidence? Critical values of G can be found in this table. + TOOLS x10 The potential outlier should be rejected. The potential outlier should be kept. Based on the outcome of the Grubbs test, calculate the mean (x), standard deviation (s), and 99% confidence interval for the results. A list of t values can be found in the Student'st table. ppm S = Ppm confidence interval: ppm
- 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. Construct a frequency distribution Difference in Length -0.005 but less than -0.003: -0.003but less than -0.001 -0.001but less than 0.001 0.001but less than 0.003 0.003but less than 0.005 Frequency Difference Between Actual and Specified Lengths 0.002 0 -0.003…An experiment was conducted to study the extrusion process of biodegradable packaging foam. Two of the factors considered for their effect on the foam diameter (mm) were the die temperature(145°C vs.155°C) and the die diameter (3 mm vs. 4 mm). The results are in the accompanying data table.
