Explanation / Answer
Conclusions:
1. As p value ( 0.021) is less than alpha value ( 0.05), we can reject the null hypothesis.
2. F value is also greater ( 4.409) than Fcrit ( 3.23) means that null hypothesis is rejected.
3. We can conclude that all of population means are not equal and some of the means are statistically significant.
