7. Using the following data, determine the percentage retained, cumulative percentage retained, and percentage passing for...
1. Plot particle size distribution curve (You are supposed to fill the above table using MS Excel, therefore any error in the values will return zero point from the table). 2. Determine the fineness modulus of the sample and comment on what that means. 3. Based on the results of the sieve analysis, is the batch of aggregates suitable for making concrete? You are expected to go to the library to find out about grading requirements of aggregates. You can...
sieve
analysis
The results of sieve analysis are as follows: Determine the percent finer than each sieve and plot the grain-size distribution curve Determine D10, D30 and D60 from the grain size distribution curve Calculate the uniformity coefficient and coefficient of gradation Determine the percentages of gravel, sand and fines using the AASHTO system and the USCS.
An available stock fiter sand has the following sieve analysis: Table 2: stock fiter sand Size, mm Cumulative weight, % 0.13 2.5 52.0 63.0 84.0 93.0 97.0 100.0 3.36 4.34 a. Determine the geometric mean size, the geometric standard deviation, the effective size and the uniformity coefficient for the stock sand. b. It is desire to produce from this sand with an effective size of 0.6 mm and uniformity coefficient of 1.5. What U.S. Standard sieve size would be used...

Problem 5 (20 points) Control Chart You are the manager of an asphalt batch plant. You are evaluating quality control test data for a highway paving project. The design specifies an asphalt content of 5% with a tolerance of +1.5%,-1.0%. 3 samples were taken each day for 5 days. Your lab has plotted the test data for the last week. Asphalt Sample...
The following table shows the lab results of a grain size analysis and Atterberg limits for an inorganic soil sample (initial total mass=1029) Assume you measured a liquid limit of 40% and plastic limit of 30% for the sample.

For the following exercises you can use the 'Wooldridge' package in R to load the data 9. (7 marks) (using dataset: "k401k") The data in 401K are a subset of data analyzed by Papke (1995) to study the relationship between participation in a 401(k) pension plan and the generosity of the plan. The variable prate is the percentage of eligible workers with an active account; this is the variable we would like to explain. The dummy variable sole represents whether...

2. You are studying a disorder that is based on the genetic
composition at three loci. Assume that a dominant allele at any
locus adds 7 units of risk for the disorder and that a recessive
allele at any locus adds 3...
2. The following data were collected last semester on ten students. Complete a multiple regression analysis in which you use AGE (A), MATH PROFICIENCY (MP) (on a 1 –10 scale), and GENDER (G) (0 = male, 1 = female) as predictors of FINAL EXAM (FE) performance. Do this analysis in SPSS and then answer the following questions. Subject # A MP G FE 1 35 8 1 90 2 31 6 0 88 3 26 5 1 84 4 33...
