Mice were sampled from 10 populations between 3 and 10 mice

Mice were sampled from 10 populations (between 3 and 10 mice per population) and their lengths recorded. A 1-way ANO VA indicated that there is a statistically significant difference in the mean length among these 10 populations, so a post-hoc test (Tukey\'s HSD) was conducted. The results are summarized in the table below. Use this information to answer the questions that follow. Based on Tukey\'s MCP, are the mean lengths for Populations 1 and 5 significantly different? Based on Tukey\'s MCP, are the mean lengths for Populations 4 and 9 significantly different? Based on Tukey\'s MCP, are the mean lengths for Population 3 and 5 significantly different?

Solution

Groups 1 and 5 are in the same TUKEY
