An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures

. there were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting. the entries in the accompanying anova table are based on information in an article. fill in the remaining entries. (round your answer for f to two decimal places.)

Assuming  there were 26 measurements on concrete cylinders for each mixture. Alternative Hypothesis at α=0.01 will be rejected.

<h3>Hypothesis</h3>

Electrical resistivity(I)=6

Concrete cylinder measurement(J)=26

First step

Degree of freedom for  SSb=I-1=(6-1)=5

Degree of freedom for SSw=I(1-J)=6(1-26)=150

Degree of freedom for SSr=IJ-1=(6×26)-1=155

Second step

Mean square(MSw)=13.929

SSw=MSw×I(J-1)

SSw=13.929×150

SSw=2,089.35

Third step

SSb=SSt-SSw

SSb=5,664.415-2,089.35

SSb=3,575.065

Fourth step

MSb=SSb(I-1)

MSb=3,575.065/(1-6)

MSb=3,575.065/5

MSb=715.013

Fifth step

F=MSb/Msw

F=715.013/13.929

F=51.33

The complete table is:

Source   df      Sum of squares       Mean square      F

Mixture    5         3,575.065                715.013              51.33

Error        150       2,089.35                 13.929

Total       155       5664.415

Therefore, since 51.33 is greater than 11.97 we are going to reject the hypothesis at α=0.01.

Inconclusion Hypothesis at α=0.01 will be rejected.

In a few sentences, describe how sedimentary rock forms.
photoshop1234 [79]

answer:

sedimentary rock is formed when rocks start to weather away causing them to loosen. **weathering is the breaking down of rocks, soils, minerals, and artificial materials through contact with water, atmospheric gases, and biological organisms.** sedimentary rocks are formed from older rocks. the pieces of broken rocks are then transported (through water.) and over time the layers will become compacted (salt crystals 'glue' the layers together.)

good luck :)

i hope this helps

have a nice day!
