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
Answer:
Option C. 4.2 units
Step-by-step explanation:
Diagonals of a square intersect each other at 90°.
Therefore, From the right angle triangle formed at the center will be,
(Length of square)² = 3² + 3² [By Pythagoras theorem}
Length of the square =
= 4.24 units
≈ 4.2 units
Option C is the answer.
