Consider the following information. SSTR = 6750 H0: μ1 = μ2 = μ3 = μ4 SSE = 8000 Ha: At least one mean is different If n = 5, the mean square due to error (MSE) equals a. 1687.5. b. 400. c. 500. d. 2250.

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

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
