Sample 1 has lower weight percentange than sample 2 for the same sizes of soil grains is the wrong option
Sizes of soil grains are different for each sample. Thats the reason why for same percentage of passing, for both samples sieve size will be different
Add Answer to:
please answer ASAP

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...

Q2) Paired-Samples t Test (14 points) A research project has been tracking the health and cognitive functions of the elderly population in Arizona. The table below shows the memory test scores from 10 elderly residents, tested first when they were 65 years old and again when they were 75 years old. The researcher wants to know if there is a significant decline in memory functions from age 65 to age 75 based on this sample. In other words, it is...
