Answer:
Treatment remains the same. Do not Reject.
Step-by-step explanation:
Test Statistics:
[tex]f = \frac{\text{treatment}}{\text{error}} = 5.37[/tex]
Reject Null Hypothesis if [tex]f > f(a, a-1, N-a)[/tex]
Critical Value [tex]f(0.01, 3, 15) = 5.42 \text{ (From F Table)}[/tex]
[tex]\because 5.37 < 5.417[/tex]
We fail to Reject [tex]H0[/tex]
[tex]\therefore[/tex] Do not Reject.
