Given the 2.5 in diameter microstructure depicted below at 200x magnification, find the grain size number.
2. The photomicrograph below, taken at a magnification of 150X, shows the microstructure of annealed palladium. a) Determine the ASTM grain size number of the palladium. b) Using at least four randomly drawn lines, determine the average grain size using the intercept method.
Determine the ASTM grain size number if 90 grains per square inch are measured at a magnification of 65x, Part 1 In this problem, you are asked to find the ASTM grain size number given the number of grains per square inch and the magnification.

Question 12 Current Attempt in Progress Determine the ASTM grain size number if 32 grains per square inch are measured at a magnification of 250x
2. Grain size distribution curves are illustrated below for four different soils. For each soil sample determine D10, D30, D50, D60, Cu, cc, %Gravel, %Sand, and %Fines. Also, if possible and appropriate, comment on the gradation characteristics of each sample (i.e. well, poor, uniform, etc.). Recall that you may not be able to determine D1o, D3o, and/or D6o for all of the samples. 100 -O- Soil 1 -- Soil 2 -Soil 3 Soil 4 90 0 80 0 70 60...
The results from a sieve analysis are shown below. Plot the grain size distribution data using a computer on a semi-log plot (% finer on y-axis vs log of particle size in mm on the x-axis – you can download the plot from the lab 2 material). You can draw the curve through the points by hand. Show how you obtained the values you plotted. Sieve Number Mass of soil retained (g) 4 0 10 38 20 62 40 90...

1.Given below are the number of successes and sample size for a simple random sample from a population. x= 7, n = 50, 98% level. the 98% confidence interval is from _ to _.
Test a hypothesis H0: μ=50; H1: m≠50 at α=0.10. Given σ=2.5 and a sample of size 30 was taken and the sample means X-bar=47.5. You can use P-value to test or find zα/2 to do the test.
The number of successes and the sample size are given for a simple random sample from a population. Use the one-proportion plus-four z-interval procedure to find the required confidence interval. n = 188, x = 157; 95% level 0.785 to 0.871 0.786 to 0.870 0.774 to 0.882 0.775 to 0.881
