Answer:
there were 10 individuals in each treatment
Explanation:
In analysis of variance, the F- value from the table is gotten by using the degree of freedom for treatment and degree of freedom for error. for this question, lets assume k to be the number of treatments and N to be total number of samples.
to get degree of freedom for treatment = K - 1 = 2 in this case. thus,
K= 2 + 1 =3. there are 3 treatments.
to get the degree of freedom for error, N - K is used. in this case.
N - 3 = 27. thus N = 30. the total number of samples is 30 and the number of treatment is 3. to get the number of individuals in a treatment, divide the total number of samples by the number of treatments = 30/3 = 10
