Expert Solution

Step 1

ANOVA: The analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the population means ( $μ$ ) of more than two independents (unrelated) groups.

The null and alternative hypothesis are,

H₀: There is no significant difference between the treatment means ( $μ$ ).

H₁: At least one treatment differs significantly.

$H_{0} : μ_{1} = μ_{2} = μ_{3} = μ_{4} H_{1} : μ_{1} \neq μ_{2} \neq μ_{3} \neq μ_{4}$
