Answer:
(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:
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).
The given equation is,
Simplifying the above equation,
Therefore, the factors of the given expression is 4(x-1)(x-12).
