Answer:
The correct answer is - false.
Explanation:
Tukey's range test also called Tukey's method or Tukey's test or Tukey's HSD (honestly significant difference). It is a one-step method or test to compare multiple comparisons and based on statistical values.
Tukey's HSD can also be used to check if that is significantly different from one treatment to another. In this given question all groups differ by more than HSD, so every single treatment is significantly different from the other.
Thus, the correct answer is - false.
