Answer:
d. 2250.
Step-by-step explanation:
The calculation of mean square due to error (MSE) is shown below:-
Since there are four treatments i.e H0: μ1 = μ2 = μ3 = μ4
And, the SSTR is 6,750
Based on this, the mean square due to error is
= 

= 
= 2,250
Hence, the mean square due to error is 2,250
Therefore the correct option is d.
All the other information is not relevant. Hence ignored it
Add all the clay together and divide it by 5 so the answer is 13
Use the ! tool to find the # of combinations.
8!/5! = 40,320/120 = 336
First, we find the volume of the pool.
3.8*5.5*1.2= 25.08.
Then we convert the feet into gallons.
25.08*7.5 = 188.1
The pool will hold 188.1 gallons of water.
