(1) The between groups degrees of freedom is 2.

(2) TRUE.

(3) The correct option is (a).

Step-by-step explanation:

(1)

The between groups degrees of freedom for the study is:

\text{df}_{B}=k-1\\=3-1\\=2

Thus, the between groups degrees of freedom is 2.

(2)

The hypothesis for he one-way ANOVA is:

<em>H</em>₀: All the means are equal.

<em>Hₐ</em>: At least one of the mean is not equal.

The output of the ANOVA test is attached below.

The <em>p</em>-value of the test is 0.00005.

<em>p</em>-value = 0.00005 < <em>α</em> = 0.05

Thus, the result is statistically significant.

The statement is TRUE.

(3)

As the <em>p</em>-value of the test is less than the significance level, the researcher should make the decision to reject the null hypothesis.

The correct option is (a).
